Centripetal force may be equal to
Correct answer: D. All of these
- A. mv2/r
- B. pv/r
- C. p2/mr
- D. All of these
Explanation
The correct answer is Option D: All of these. All options are correct in the context of centripetal force. Option A represents the formula for centripetal force, Option B attempts to express it in terms of momentum, and Option C also tries to simplify the formula using momentum.

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.
