Physics · SYSTEMS OF PARTICLES AND ROTATIONAL MOTION
हिन्दीA torque \( \tau \) acting on a body produces an infinitesimal angular displacement \( d\theta \). The work done \( dW \) by the torque is expressed as:
Correct answer · Option 1
\( dW = \tau \, d\theta \)
Explanation
Work done by a torque in rotational motion about a fixed axis is analogous to linear work \( dW = F \, ds \), given by \( dW = \tau \, d\theta \).
