4. Two point charges q and -q are placed at points (0, 0, a) and (0, 0, -a) respectively. (i) Find potential and electric field due to these charges at point (r. 0, 0). (ii) Find the leading term of the potential and electric field in the limit r >> a. (iii) If these charges are places inside a grounded conducting sphere of radius R, find the potential and electric field inside the sphere. (iv) Find the induced charge density on the sphere.
