Question

What is the effect of a force applied at the axis of rotation on a rigid body?

Options

Choose one · Correct answer highlighted

Explanation

A force applied at the axis (r = 0) produces no torque (τ = rFsin⁡θ = 0), so it cannot cause rotation about that axis. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It causes no rotation. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
