II. Three particles - each with a charge of q = +2µC – are held fixed to form a right triangle, as shown. A) What is the net Coulomb force

on Particle 2? Remember to give your answer as a vector. B) What is the electrostatic potential energy of the system? C) If a neutral metal sphere were brought close to Particle 2, as shown, what would the charge distribution on the sphere be like? Please explain your reasoning.
