using vectors, i make the electric field E = -lamda/2pi(sqrt.[r^2-s^2])epsilon r^2 = s^2 +(c-a)^2, (and b is c-a), therefore rearrange, (c-a)^2 is (r^2-s^2) does this help?

and is the normal force the vector sum of Mg and the orginal equation i quoted for the acceleration of the wedge?

so is it mg - the vertical value for the normal force?

Ive got mg as one component, and I know the horizonal so what other components should I include?

Right ok, I've figured out the horizonal acceleration of the block, swapping the negative for a postive, (as the accelerations of each are away from each other). Then times the equation by M, divide through by small m to get a, acceleration of block. So how would I go about getting the...

I derived the frist equation myself with great difficulty. Now I have to find the horizontal and vertical acceleration of the block. So I thought the acceleration of the block is equal to the acceleration of the wedge (as you pointed out Newton's Third Law - opposite and equal reactions). The...
