A body is moving in a circle at constant speed. Which statement is true?

Explanation

If a moving object has no forces acting on it, it will continue to move in a straight line at constant velocity. So, if an object is moving in a circle, or along the arc of a circle, it follows that there must be a force acting on it to change its direction. In order for the object to move on a circular path, the force must always be acting toward the center of the circle. When we turn around a corner or around an arc using a motorcycle, car,s, etc; we compel the body to move in such motion. The force which compels the body to move in a circle is called center-seeking force or centripetal force. Hence, A is the correct option.
