Which statement is correct?
The work done by an external force in moving a probe from PPP to QQQ is greater than the work done in moving the same probe from PPP to RRR.
The gravitational field strength at point QQQ is equal to the gravitational field strength at point RRR.
No net work is done by the gravitational field when a satellite moves along the path P→Q→RP \rightarrow Q \rightarrow RP→Q→R.
The work done by an external force to move a mass from PPP to QQQ is equal to the work done to move the same mass from PPP to RRR.
