Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x " #50 cm and x " )50 cm. the charge densities on the planes are #50nc/m2 and )25 nc/m2 , respectively. what is the magnitude of the potential difference between the origin and the point on the x axis at x " )80 cm? (hint: use gauss’ law.)
