$A$ body has a constant speed but it can have a varying velocity.

Vedclass · Answer

(B) Velocity is a vector quantity,meaning it has both magnitude (speed) and direction. For velocity to be constant,both magnitude and direction must remain constant.If a body has a constant speed,its velocity can still vary if its direction changes. $A$ classic example is uniform circular motion,where the speed is constant,but the direction of motion changes at every point,resulting in a changing velocity and the presence of centripetal acceleration.Option $A$ is incorrect because constant velocity implies constant speed.Option $B$ is correct because a body moving in a circle at a constant speed has a varying velocity due to the continuous change in direction.Option $C$ is incorrect because a body with constant speed in a circular path experiences centripetal acceleration.Option $D$ is incorrect because if a force acts perpendicular to the displacement (like centripetal force),the work done is zero.
