Question

Centripetal force :
(a) can change speed of the body.
(b) is always perpendicular to direction of motion
(c) is constant for uniform circular motion.
(d) all of these

Answer 1

Answer:

(d) All of these

Explanation:

Since the centripetal force is center-seeking force that tends to pull object at the center if its more the speed will surely change as it is always perpendicular to motion of  the object moving in circular motion. And also it is constant  in UCM (Uniform Circular Motion)
