Physics System of Particles Rotational Motion Mix MCQ (Single Correct)

A uniform rod kept vertically on the ground falls from rest. Its foot does not slip on the ground.

No part of the rod can have acceleration greater than g in any position.

At any one position of the rod, different points on it have different accelerations.

Any one particular point on the rod has different accelerations at different positions of the rod.

The maximum acceleration of any point on the rod, at any position, is 1.5 g.

The correct answer is:

CHECK THE SOLUTION.

(b, c, d)

Taking torque about A, when the rod has fallen through an angle θ θ .

τ τ = mg sin θ θ - I α α =

or α α =

For any point P on the rod, at a distance r from A, the linear acceleration is

a = r α α =
