A planet is moving around the sun in an elliptical orbit at different positions A, B, C, D. The maximum rotational kinetic energy of a planet is at postion.
Options:
Answer:
D
Solution:
Concept: Angular momentum is always conserved as the torque (or forces) between sun and the planet is internal. When a planet is closest to the sun ( is minimum), it attains its highest orbital velocity ( is maximum), thus attaining maximum Kinetic Energy. So, the K.E of the planet will be maximum at point C.
