Question

An object is taken from a point P to another point Q in a gravitational field.

Solution

The correct options are

**A** Assuming the earth to be spherical, if both P and Q lie on the earth's surface, the work done is zero

**C** The work done depends only on the position of P and Q and is independent of the path along which the particle is taken

**D** There is no work done if the object is taken from P to Q and then brought back to P along any path

Gravitational field is conservative ⇒work done to move an object in closed loop=0

Gravitational field is conservative ⇒work done to move an object in closed loop=0

And work done in moving a mass from one location to another is independent of path.

∴A,C and D are correct.
