Which of the following diagrams 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 ExpertsThe correct answer is:
D
When the earth is closest to the sun, speed of the earth is maximum, hence kinetic energy is maximum.
When the earth is farthest from the sun, speed is minimum, hence kinetic energy is minimum but it will never be zero and negative.
This variation is correctly represented by option .
