Assertion: A pendulum is oscillating between points A , B and C . Acceleration of bob at points A or C is zero.
Reason: Velocity at these points is zero.
Options:
Answer:
D
Solution:
The Assertion is false: at the extreme points A and C the velocity is zero, so the radial acceleration is zero,
but the tangential acceleration is non-zero, so the acceleration is not zero.
The Reason is true: the velocity does vanish at the extremes.
