Assertion: In vertical circular motion, the acceleration of the bob at the lowest point is directed straight up.
Reason: At the lowest point the tangential component of acceleration is zero.
Options:
Answer:
A
Solution:
At the lowest point gravity is along the radius (vertical), so the tangential component is zero (Reason true);
the only acceleration is the radial part pointing up towards the centre (Assertion true), and the Reason explains the Assertion.
