An a–particle and a proton are released from the centre of the cyclotron and made to accelerate. When they are accelerated in turn, which of the two will have higher velocity at the exit slit of the dees?

An a–particle and a proton are released from the centre of the cyclotron and made to accelerate. Can both be accelerated at the same cyclotron frequency? Give reason to justify your answer.

A pair of parallel horizontal conducting rails of negligible resistance shorted at one end is fixed on a table. The distance between the rails is L. A conducting massless rod of resistance R can slide on the rails frictionlessly. The rod is tied to a massless string which passes over a pulley fixed to the edge of the table, A mass m, tied to the other end of the string hanges vertically. A constant magnetic field B exists perpendicular to the table. If the system is released from rest, calculate. the acceleration of the mass at the instant when the velocity of the rod is half the terminal velocity.

A cricket bowler releases tha ball in two different ways giving it horizontal velocity and a small downward velocity and the speed v_s at the time of release is the same. Both are relased at a height H from the ground. Which one will have greater speed when the ball hits the ground? Neglect air resistance.

Displacement s of a particle at time t is expressed as s=1/2t^3-6t . Find the acceleration at the time when the velocity vanishes (i.e., velocity tends to zero).

Mention the significance of Davisson and Germer's experiment. An alpha-particl e and a proton are accelerated from rest through the same potential difference V. find the ratio of de-Broglie wavelength associated with them.

A cricket bowler releases the ball in two different ways (a) giving it only horizontal velocity and (b) giving it horizontal velocity and a small downward velocity. The speed v_s at the time of release is the same . Both are released at a height H from the ground . which one will have greater speed when the ball hits the ground ? Neglect air resistance.

A sphere of charge + Q is fixed in position. A smaller sphere of charge + q is placed near the larger sphere and released from rest. The small sphere will move away from the large sphere with decreasing velocity an inreasing acceleration, decreasing velocity and increasing acceleration, decreasing velocity and constant acceleration, increasing velocity and increasing acceleration explain, which of the following statements is correct?

A particle is in linear simple harmonic motion between two points, A and B, 10 cm apart. Take the direction from A to B as the positive direction and give the signs of velocity, acceleration and force on the particle when it is at the mid-point of AB going towards A,

Direction. In the follwing questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A). If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if asssertion is true, but reason if false, (D) if both assertion and reason are false Assertion : the drift velocity of electrons in a conductor is very small, when its two ends are connected to a battery. Reason : It is because, as the electrons accelerated , they get scattered or defleted on suffering collisions against the positive ions in the conductor
