Which statement is correct?
More work is done in moving a mass along the path J→L→KJ \rightarrow L \rightarrow KJ→L→K than along the direct path J→KJ \rightarrow KJ→K.
The gravitational field strength is the same at KKK and LLL.
No work is done in moving a mass from JJJ to KKK.
The work done in moving a mass from JJJ to KKK and moving it from JJJ to LLL is the same.
