NEET Physics Circular Motion Dynamics MCQ Question
A car of mass 1200 kg is moving in a circular path of radius 100 m at a speed of 20 m/s. What is the magnitude of the centripetal force acting on the car?
4800 N
2400 N
3600 N
6000 N
Correct Answer
Detailed Explanation
The centripetal force is calculated using the formula f_c = mv^2/R. Substituting m = 1200 kg, v = 20 m/s, and R = 100 m, we get f_c = (1200 * 20^2) / 100 = 4800 N.
