Question

Statement I : Even when orbit of a satellite is elliptical, its plane of rotation passes through the centre of earth.
Statement II : According to law of conservation of angular momentum plane of rotation of satellite always remain same.

• A. If both statement I and statement II are true and statement II is the correct explanation of statement I
• B. If both statement I and statement II are true but statement II is not the correct explanation of statement I
• C. If statement I is true but statement II is false
• D. If both statement I and statement II are false

Answer 1

Answer: (A)

As no torque is acting on the planet, its angular momentum must remain constant in magnitude as well as direction. Therefore, plane of rotation must pass through the centre of earth.
