C)only if it is moving with constant acceleration.
D)if it is either at rest or moving with constant velocity.
E)if it is moving with either constant velocity or constant acceleration.

Question

Quizplus · Accepted Answer

For a body to be in translational equilibrium, the net force acting on it should be zero. This means that there is no acceleration, which can be the case if the body is at rest or moving with constant velocity (as there is no change in velocity, there is no acceleration). Therefore, the correct choice is D, stating that the body can be either at rest or moving with constant velocity.
