1. Derive the electric field due to a dipole. Explain all the steps.

2. A sphere with radius 2 cm is placed at a location near a point charge. The sphere has a charge of -9*10^(-10) C spread uniformly over its surface.The electric field due to the point charge has a magnitude of 470 N/C at the center of the sphere. What is the magnitude of the force on the sphere due to the point charge?
