NEET Physics Circular Motion Dynamics MCQ Question
What is the formula for centripetal force acting on a body moving in a circle of radius R with mass m and speed v?
f_c = mv^2 / R
f_c = mR^2 / v
f_c = Rv^2 / m
f_c = mv / R^2
Correct Answer
Detailed Explanation
The centripetal force f_c that provides the inward acceleration for a body in circular motion is given by the formula f_c = mv^2 / R, where m is the mass of the body and v is its speed, as stated in the NCERT context.
