Assertion : A particle may be momentarily at rest and yet have non-zero acceleration.
Reason : The zero velocity of a particle at any instant does not necessarily imply zero acceleration at that instant.

A

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

B

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

C

If assertion is true but reason is false.

D

If both assertion and reason is false

Text Solution

Verified by Experts

The correct Answer is:
(a)
A particle may be momentarily at rest and yet have non-zero acceleration. For example, a particle thrown up has zero velocity at its uppermost point but the acceleration at that instant continues to be the acceleration due to gravity.

The velocity of a particle is zero at t=0

Assertion : A body is momentarily at rest at the instant it reverses the direction. Reason : A body cannot have acceleration if its velocity is zero at a given instant of time.

Can a body have zero velocity and finite acceleration?

If the instantaneous velocity of a particle is zero, will its instantaneous acceleration be necessarily zero

Assertion : An object may have varying speed without having varying velocity. Reason : If the velocity is zero at an instant, the acceleration may not be zero at that instant.

Assertion : Average velocity can’t be zero in case of uniform acceleration. Reason : For average velocity to be zero, a non zero velocity should not remain constant.

The velocity of a particle at an instant "t" is v=u+at ,where u is initial velocity and a is constant acceleration.The v -t graph are

Assertion: If velocity of a particle at a certain instant is zero then its acceleration must also be zero at the same instant. Reason: When a particle is projected upward under gravity then at the top point its instantaneous velocity becomes zero.

Assertion: If a body is momentarily at rest, it means that force or acceleration are necessarily zero at that instant. Reason: Force on a body at a given time is determined by the direction of motin only.
