Quizplus · Accepted Answer

If the sum of the torques on a body about a fixed axis is not zero, it means that there is a net torque acting on the body. According to Newton's second law of motion for rotational motion, a net torque will cause an angular acceleration in the body. Therefore, the correct choice is B, which states that the body experiences angular acceleration.
