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

(a) (##JMA_CHMO_C10_068_O01##).

B

(b) (##JMA_CHMO_C10_068_O02##).

C

(c ) (##JMA_CHMO_C10_068_O03##).

D

(d) (##JMA_CHMO_C10_068_O04##).

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `K.E=1/2k(A^(2)-d^(2)`
and P.E.=1/2kd^(2)`
At mean position `d=0`. At extremes positions `d=A`.
