Oh am sorry, I don't know why assumed the height to be 6, nevermind.

Is that 6 ? or the coordinate on y axis (0,6) ?

coordinate on y axis.

I see, then use the given eqn, find coordinates of x, as I said before, they should come out to be (6,6) and (6,6)

you should also be able to find out direction of force, can you tell me what will that be ?

Note that direction of force is different at different points on the force, j is the direction of net force. Anyways, glad to help.
