Assertion : When an automobile while going too fast around a curve overturns, its inner wheels leave the ground first.
Reason : For a safe turn the velocity of automobile should be less than the value of safe limit velocity.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts

The correct Answer is:
B
When automobile moves in circular path then reaction on inner wheel and outer wheel will be different.
`R_("inner") = M/2 [g - (v^(2)h)/(ra)]` and `R_("outer") = M/2[g + (v^(2)h)/(ra)]`
In critical condition
If v is equal or more than the critical value then reaction on inner wheel becomes zero. So it leaves the ground first.

TRUE/FALSE TYPE QUESTIONS: When an automobile going fast around a curve overturns, its outer wheels leave the ground.

Assertion : A safe turn by a cyclist should neither be fast nor sharp. Reason : The bending angle from the vertical would decrease with increase in velocity.

Assertion When a car takes a circular turn on a horizontal road, then normal reaction on inner wheels is always less than the normal reaction on outer wheels. Reason This is for rotational equilibrium of car.

Assertion : The tendency of skidding or overturning is quadrupled, when a cyclist doubles his speed of turning. Reason : Angle of bending measured from ground., decreases as velocity of vehicle increases.

Assertion : As the frictional force increases, the safe velocity limit for taking a turn on an unbanked road also increases. Reason : Banking of roads will increase the value of limiting velocity.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion A block of mass m starts moving on a rough horizontal surface with a velocity v. It stops due to friction between the block and the surface after moving through a certain distance. The surface is now tilted to an angle of 30^(@) with the horizontal and the same block is made to go up on the surface with the same initial velocity v. The decrease in the mechanical energy in the second situation is smaller than that in the first situation. Reason The coefficient of friction between the block and the surface decreases with the increase in the anglle of inclination.

The French physicist Louis de Broglie in 1924 postulated that matter like radiation , should exhibit a dual behaviour. He proposed the following relationship between the wavelength .lambda of a material particle,its linear momentum P and Planck constant h. lambda=(h)/(p)=(h)/(mv) The de Broglie relaion that the wavelength of a particle should decrease as its velocity increases. It also implies that for a given velocity heavier particles should have shorter wavelength than lighter particles.The waves or de Broglie waves. These waves differ from the electromagnetic waves as they: (i) have lower velocities (ii) have no electrical and magnetic fields and (iii) are not emitted by the particle under consideration. The expermental confirmation of the de Broglie relation was obtained when Davission and Germer in 1927, observed. As diffraction is a characteristic property of waves, hence the beam of electrons behave as a wave as proposed by de Broglie. Werner Heisenberg considered the limits of how precisely we can measure properties of an electron or other microscopic particle like electron . He determined that there is a fundamental limit of how closely we can measure both position and momentum. The more accurately we can determine its position. The converse is also true. This is summed up in what we now call the ''Heisenberg uncertainty principle'' : It is impossible to determine simultaneously and precisely both the momentum and position of a particle. The product of uncertainty in the position, Deltax and the uncertainty in the momentum Delta(mv) must be greater than or equal to (h)/(4pi), i.e., Deltax Delta(mv)ge(h)/(4pi) The transition so that the de Broglie wavelength of electron becomes 3 times of its initial value in He^(+) ion will be :

The waves associated with particles in motin are called matter waves or de Broglie waves. These waves differ from the electromagnetic waves as they (i) have lower velocities have no electrical and magnetic fields and are not emitted by the particle under consideration. The experimental confirmation of the de Broglie relation was obtained when Davisson and Germer. in 1927, observed that a beam of electrons is diffracted by a nickel arystal. As diffarceted by a nickel . As diffraction is a characteristic property of waves, hence the beam of electron dehaves as a wave, as proposed by de Broglie. Werner Heisenberg cobnsiderd the imits of how precisely we can measure propoerties of an electron or other microscopic particle like electron. he determined that there is accurately we measure the momentum of a particle, the less accurately we can determine its position .

An inquistive student, determined to test the law of gravity for himself, walks to the top of a building og 145 floors, with every floor of height 4 m, having a stopwatch in his hand (the first floor is at a height of 4 m from the ground level). From there he jumps off with negligible speed and hence starts rolling freely. A rocketeer arrives at the scene 5 s later and dives off from the top of the building to save the student. The rocketeer leaves the roof with an initial downward speed v_0 . In order to catch the student at a sufficiently great height above ground so that the rocketeer and the student slow down and arrive at the ground with zero velocity. The upward acceleration that accomplishes this is provided by rocketeer's jet pack, which he turns on just as he catches the student, before the rocketeer is in free fall. To prevent any discomfort to the student, the magnitude of the acceleration of the rocketeer and the student as they move downward together should not exceed 5 g. What should be the initial downward speed of the rocketeer so that he catches the student at the top of 100 the floor for safe landing ?
