When a body moves with a constant speed along a circle

Question

When a body moves with a constant speed along a circle (A) no work is done on it (B) no acceleration is produced in it (C) its velocity remains constant (D) no force acts on it

If the speed is constant then no force is acting in tangential direction. Only force acting is perpendicular to direction of velocity. Hence, work done will be zero.

Q. When a body moves with a constant speed along a circle

no work is done on it

no acceleration is produced in it

its velocity remains constant

no force acts on it

If the speed is constant then no force is acting in tangential direction. Only force acting is perpendicular to direction of velocity. Hence, work done will be zero.
