PhysicsSystems of Particles and Rotational MotionJEE Main

Assertion: Even when the orbit of a satellite is elliptical, its plane of rotation passes through the centre of the earth. Reason: According to the law of conservation of angular momentum, the plane of rotation of the satellite always remains the same.

Answer: (A)

Solution

Since no external torque acts on the satellite (gravity is always directed towards the earth's centre), its angular momentum vector — both
