A point charge is at the origin, and a second point charge is at the point x =1.2 m, y = 2.5 m. (a) Find the x and y coordinates of the position at which an electron would be in equilibrium. (b) Find the x and y coordinates of the position at which a proton would be in equilibrium. (c) Suppose the charges were both doubled. How would your answers change? Why?
