Two fixed charges of magnitude $+ 2 Q$ and $+ 6 Q$ repel each other with a force $F$ . An additional charge of $- 4 Q$ is given to each charge.

What are the magnitude and the direction of the force between the charges?

	Magnitude of force	Direction of force

$F3\frac{F}{3}$ | repulsive

$3 F$ | attractive

$3 F$ | repulsive

$F3\frac{F}{3}$ | attractive
