Two point charges of +2 × 10-19 C and +8 × 10-19 C are separated by a distance of 2 metre. Find the point on the line joining them at which the electric field is zero.

Expert Answer
Let P be the point at distance x from A, where the electric field is zero.
At x = -2 is not possible, because electric field due to both charges will be in same direction. So x = -2 m is not a possible solution.
Hence electric field is zero at 2/3 m to the right of charge q1.
