Question

A satellite 'S' is moving in an elliptical orbit around the earth. The mass of the satellite is very small as compared to the mass of the earth. Then

• A. the acceleration of 'S' is always directed towards the centre of the earth
• B. the angular momentum of 'S' about the centre of the earth changes in direction, but its magnitude remains constant
• C. the total mechanical energy of 'S' varies periodically with time
• D. the linear momentum of 'S' remains constant in magnitude

Answer 1

The correct option is A the acceleration of 'S' is always directed towards the centre of the earth

The acceleration of 'S' is always directed towards the centre of the earth.
