C

If Assertion is true but Reason is false

D

If Assertion is false but Reason is true

Text Solution

Verified by Experts

The correct Answer is:

    A : Angular momentum of a satellite about a planet is constant . R :Gravitational force is a central force so its torque about the sun is zero .

    Assertion: For the plantes orbiting around the sun, angular speed, linear speed, K.E. changes with time, but angular momentum remains constant. Reason: No torque is acting on the rotating planet. So its angular momentum is constant.

    Assertion The angular momentum of system always remain constant. Reason For a system, tau_(ext)=(dL)/(dt)=0

    Assertion : If a particle moves with a constant velocity, then angular momentum of this particle about any point remains constant. Reason : Angular momentum has the units of Plank's constant.

    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.
