three point charges q1,q2&q3 are place at the vertices of triangle as shown in the diagram charge q1 has been given 4.5 X 10^13 extra electrons, charge q2 given 9.0 X10^13 extra electrons and q3 has had 9.0 X 10^13 electrons taken from it. Calculate the electric charge of q1,q2,&q3?

1stly i use the formula V=u/q to find the charge but it doesn't work,so i'm stuck with it!!
