An object is attached toward the origin with a force given by `F=-k//x^(2)` Calculate the work done by the force F when the object moves in the x - direction from `x_(1)` to `x_(2)` if `x_(2) gt x_(1)` is the work done by F positive or negative ? You now exert a force with your hand to move the object slowly from `x_(1)` or `x_(2)`
