A plantet is moving round the sun in an elliptical orbit as shows. As the planet moves from `a` to `B`

A

its kinetic enargy will decrease

B

its potential energy will remain unchanged

C

its angular momentum about centre of sun will remain unchanged

D

its speed is minimum at `A`

Text Solution

Verified by Experts

The correct Answer is:
C, D
At maximum distance (at `A` ) kinetic energy is minimum. But angular momentum about centre of sun always remains constant.
