how can we show that work done by conservative force such as a spring force in a cyclic process is zero.

A force is said to be conservative if work done in taking the system from one point to the other point is independent of path followed but depends upon initial and final position.
 
Now, in case of cyclic process the initial and final positions are same, which means that the displacement is zero. Now, since the displacement is zero work done by conservative force such as a spring force in a cyclic process is zero.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
