Answer:


r=7* 10^(-16)\ m

Step-by-step explanation:

The force between charges,
F=-4.4* 10^(33)\ N

Positive charge,
q_1=8* 10^(-4)\ C

Negative charge,
q_2=-3* 10^(-4)\ C

We need to find the distance between charges. The force of attraction between charges is given by :


F=(kq_1q_2)/(r^2)

Where

r is the distance between charges


r=\sqrt{(kq_1q_2)/(F)} \\\\r=\sqrt{(9* 10^9* 8* 10^(-4)* 3* 10^(-4))/(4.4* 10^(33))} \\\\r=7* 10^(-16)\ m

So, the distance between charges is
7* 10^(-16)\ m.
