Solution

The correct option is D keep the body in uniform velocity
According to law of inertia or Newton’s first law of motion, a body in state of rest or of uniform motion remains in state of rest or of uniform motion unless it is acted upon by an external force. Hence, a body in uniform motion requires no force to keep it in uniform motion.

Q. In which case of a moving body, force is not needed?

The velocity of a body moving in a straight line is increased by applying a constant force F, for some distance in the direction of motion. Prove that the increase in kinetic energy of the body is equal to the work done by the force on the body.

The velocity of a body moving in a straight line is increased by applying a constant force $F$ , for some distance in the direction of the motion. Prove that the increase in the kinetic energy of the body is equal to the work done by the force on the body.
