The centripetal force is zero when the centrifugal force is _.
Correct answer: B. Zero
- A. Equal
- B. Zero
- C. Maximum
- D. None of these options are correct
Explanation
Option B is correct since centripetal force and centrifugal force are equal in magnitude and opposite in direction, so it will also be zero.

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.
