Assertion: When the velocity of projection of a body is made `n` times, its time of flight becomes `n` times.
Reason: Range of projectile does not depend on the initial velocity of a body.

A

If both the assertion and reason are true and reason is a true explantion of the assertion.

B

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

C

If the assertion is true but reason false

D

If both the assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
`T prop u and R prop u^(2)`
When velocity of projection of a body is made n times, then its time of flight becomes n times and range becomes `n^(2)` times.

    In the following questions, a statement of assertion is followed by a statement of reason (R). Mark the correct choice as : Assertion. For a projectile the time of flight of a body becomes n times the original value if its speed is made n times. Reason. For a projectile, this is due to the range of the projectile which becomes n times.

    Assertion : If time of flight in a projectile motion is made two times, its maximum height will become four times. Reason : In projectile motion H prop T^2 , where H is maximum height and T the time of flight.

    Assertion (A): When the distance between the parallel plates of a parallel plate capacitor is halved and the dielectric constant of the dielectric used is made three times, then the capacitance becomes three times. Reason (R ): Capacitance does not depend on the nature of material.

    In _________ motion of a body its velocity varies with time.

    Assertion: The height attained by a projectile is twenty five percentage of range, when projected for maximum range. Reason: The height is independent of initial velocity of projetile.
