Question

Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x = -51 cm and x = +51 cm. The charge densities on the planes are -60 nC/m² and +28 nC/m², respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x = +87 cm? (Hint: Use Gauss' law for planar symmetry to determine the electric field in each region of space.)
