AIIMS 2001 Physics Centripetal Force MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A particle is revolving in a circle of radius R. If the force acting on it is inversely proportional to R, then the time period is proportional to
A
R
B
R²
C
1/R
D
1/R²
Correct Answer
Option A
Detailed Explanation
Centripetal force F ∝ 1/R implies T² ∝ R³ (Kepler's third law), so T ∝ R^(3/2).
