What is the minimum velocity with which a body of mass m must enter a vertical loop of radius R so that it can complete the loop?
A
√3gR
B
√5gR
C
√gR
D
√2gR
Correct Answer
Option B
Detailed Explanation
The minimum velocity at the top of the loop is derived from the condition that the centripetal force is provided entirely by gravity, ensuring the body remains in contact with the track.
