Statement-1: For the planets orbiting around the sun, angular speed, linear speed, `KE` changes with time,but angular momentum remains constant.
Statement-2: No torque is acting on the rotating planet, so its angular momentum is constant.

A

B

Statement-1 is true, Statement-2 is true, statement-2 is Not a correct explanation for statement-1

C

Statement-1 is true, Statement-2 is false.

D

Statement-1 is false Statement-2 is True.

Text Solution

Verified by Experts

The correct Answer is:
a
The torque on a body is given by `vec(tau)=(dvec(tau))/(dt)`. In case of planet orbiting around the sun no torque is acting on it. `implies L` (angular momentum)=constant
