Gravitaional potential energy

Question

The earth moves in an elliptical orbit with the sun ,S at one of foci as show in figure. Its rotational kinetic energy is maximum at the point :

Moderate

A

A
B

B
C

C
D

D

Solution

Potential $KE = \frac{L^{2}}{2 I}$ where L = angular momentum
and I = moment of inertia
At A,I is minimum so rotational KE is maximum at point A.
