When an object is moved from rest at point a to rest at point b in a gravitational field, the net work done by the field depends on the mass of the object and

1. the nature of the external force moving the object from a to b.

2. the velocity of the object as it moves between a and b.

3. both the positions of a and b and the path taken between them.

4. the path taken between a and b only.

5. the positions of a and b only.

5. The positions of A and B only.

Explanation: Gravitational force or pull is the pull on all objects by the Earth Magnetic forces,it tends to attract all objects to itself. Gravitational field is a field induced by an object with mass, which will interact with other massive objects by applying a force on it . Gravitational field does not depend on the paths of motion of any object,its velocity, the nature of the forces around the object,the Gravitational force is known to be a conservative force,which tries to conserve its force.
