A gravitational field is present in a region. A point mass is shifted from `A` to `B`, along different paths shown in the figure. If `W_1, W_2` and `W_3` represent the work done by gravitational force for respective paths, then

`W_(1)=W_(2)=W_(3)`

`W_(1)gtW_(2)gtW_(3)`

`W_(1)gtW_(3)gtW_(2)`

none ot these
