Two point charges -2q and 3q are on the x-axis -2q at the, Ask an Expert

Academics

Two point charges -2Q and +3Q are on the x-axis, -2Q at the origin and +3Q at x = D. Choose the potential to equal zero at infinity. Find two points on the x-axis within the vicinity of the charges where the electric potential is zero. Show that there are no points along the y-axis where the potential is zero within a finite distance from the charges.
