(space science - sorry didn't know what subject to put it under) is it possible to manipulate a wormhole so that you can position the ends to where you want? in other words is it possible to change the destination of a wormhole?

It is possible. If you trap it in a certain space, it will be possible.

Pe = 1/2k(x)^2  and .05n/m = .05x10^-9m = x 

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
