For a simple pendulum, a graph is plotted its kinetic energy (KE) and potential energy (PE) against its displacement d. Which one of the following represents these correctly?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B
As `K.E.=(1)/(2)momega^(2)d^(2)`
and P.E. `=(1)/(2)momega^(2)d^(2)`
At `d=+-A`
P.E.`=` maximum , while K.E. `=0`
`:. `Option `(b)` is correct.
