STANDARD Physics Vertical Circular Motion Match the Following Question
A bob of mass m is suspended by a light string of length L. It is imparted a horizontal velocity v₀ at the lowest point A such that it completes a circle in the vertical plane. Match Column I with Column II.
A-r, B-s, C-q, D-p
A-q, B-r, C-p, D-s
A-r, B-s, C-q, D-p
A-s, B-p, C-r, D-q
Correct Answer
Detailed Explanation
The velocity at different points and the ratio of kinetic energies can be determined using conservation of energy and Newton's laws. At point A, the velocity is √5gL, at point B it is √3gL, and at point C it is √gL. The ratio of kinetic energy at B and C is 3.
