Answer:

-11776.36 N

This force is attractive since both charges are of opposite sign

Explanation:

Given that

q_1=-18.4\mu C=-18.4\times 10^{-6}C\ and\\\ q_2=53\mu C=53\times 10^{-6}C

Distance between the spheres = 2.73 cm =0.0273 m

where K is Coulomb's constant = 9.10^ 9 [N.m^2 /C^2]

According to coulombs law we know that force between two charges is given by

F = \frac{kq_1q_2}{r^2}

F = \frac{(9\times10^9)\times (-18.4 \times 10^-^6)(53  \times 10^-^6}{0.0273^2)} \\= -11776.36N

This force is attractive since both charges are of opposite sign
