With reference to Fig. 4-37 (P4.56), charge Q is located

With reference to Fig. 4-37 (P4.56), charge Q is located at a distance d above a grounded half-plane located in the x–y plane and at a distance d from another grounded half-plane in the x–z plane. Use the image method to
(a) Establish the magnitudes, polarities, and locations of the images of charge Q with respect to each of the two ground planes (as if each is infinite in extent), and
(b) Then find the electric potential and electric field at an arbitrary point P (0, y, z).
