If we double, both the speed of the body and radius of the circular path, the centripetal force will be:
Correct answer: B. Double
- A. Same
- B. Double
- C. 4 times
- D. 8 times
Explanation
If both the speed of a body and radius of its circular path are doubled, then centripetal force also gets doubled.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
