Which statement is correct?
The gravitational field strength is identical at points YYY and ZZZ because they lie on the same equipotential curve.
No work is done in moving a test mass from XXX to YYY because the gravitational field is conservative.
More work is done in moving a test mass along the path X→Z→YX \rightarrow Z \rightarrow YX→Z→Y than along the direct path X→YX \rightarrow YX→Y.
The work done in moving a test mass from XXX to YYY is equal to the work done in moving it from XXX to ZZZ.
