Eight +2 nC charges are placed on the vertices of a cube. The
cube is centered at Q = (0, 0, 0) the origin. The (x, y, z)
co-ordinates of the vertices are givenby the eight combinations in
(±a,±a,±a). If a = 10 cm what is the net electric field at point P
= (0, a/2 , 0)?
Sketch the situation and state the direction of net electric field
at P.
What is the electric field at the origin Q?
