The charges begin to leak from both the spheres at a constant rate. the following configurations of electric charges located at the vertices of an equilateral triangle. When the two spheres are brought near each other, they swing toward each other and touch, then swing away from each other. Two uniformely charged spheres are suspended by strings of length L from vertically adjustable supports. As a result, the spheres approach each other with a velocity v.
