For a simle pendulum, a graph is plotted between its kinetic energy (KE) and potential energy (PE) against its displacement d. Which one of the following represents these correctly ?
(Graphs are schematic and not drawn to scale)

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
`KE=1/2m omega^(2)(A^(2)-d^(2))`
`PE=1/2momega^(2)d^(2)`
At `d=pm A,` PE=maximum while KE=0
