If angular frequency is doubled, centripetal force becomes:
Correct answer: B. Four times
- A. Twice
- B. Four times
- C. Eight times
- D. Remains the same
Explanation
Fc=mrω2Fc ∝ ω2If angular frequency is doubled thenFc ∝ (2ω)2Fc ∝ 4ω2Hence,B is the correct option

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.
