A) \[mgl\sin \theta \]
B) \[mgl(1+\sin \theta )\]
C) \[mgl(1+\cos \theta )\]
D) \[mgl(1-\cos \theta )\]
Correct Answer: D
Solution :
Kinetic energy will be maximum at mean position. From law of conservation of energy maximum kinetic energy at mean position = Potential energy at displaced position Þ \[{{K}_{\max }}=mgh=mgl(1-\cos \theta )\]You need to login to perform this action.
