Which of the diagram shown in figure most closely shows the variation in kinetic energy of the earth as it moves once around the sun in its elliptical orbit ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
When the earth is at minimum distance from the sun , speed of the earth is at maximum distance from the sun speed is minimum hence , KE is minimum but never zero and negative .
This fluctuation is represented by option (D) .
