Question

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

Options

Choose one · Correct answer highlighted

It causes maximum rotation It causes no rotation Correct It increases angular velocity directly It changes the axis of rotation

Explanation

A force applied at the axis ( r = 0 ) produces no torque ( tau = r F sin θ = 0 ), so it cannot cause rotation about that axis. This follows from latest NCERT 2026-27 principle explaining the concept clearly for NEET students in simple steps as per rationalized syllabus.
