Which of the diagram shown in figures respresents variation of total mechanical energy of a pendulam oscillation in air as function of time?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
When a pendulum oscillates in air, it will lose energy continuously in overcoming resistance due to air. Therefore, total mechanical energy of the pendulum decreases continuously with time.
The variation is correctly represented by curve (c).
