Question

On applying a constant torque on a body-

• A. linear velocity increases
• B. angular velocity changes
• C. it will rotate with constant angular velocity
• D. it will move with constant velocity

Answer 1

Answer: (B)

angular velocity changes

$\begin{array}{c}\text{When we apply a constant torque on a body , that}\\ \text{body starts rotating.}\\ \text{If torque is constant, body rotates with constant angular}\\ \text{acceleration.}\\ \text{Thus, angular velocity of body changes uniformly with time.}\end{array}$
