Explanation:
Given that,
Charge 1, [tex]q_1=-22\ \mu C[/tex]
Charge 2, [tex]q_2=+46\ \mu C[/tex]
Separation between spheres, d = 2.47 cm
We need to find the magnitude of the force that each sphere experiences. It is given by the formula as follows :
[tex]F=k\dfrac{q_1q_2}{d^2}\\\\F=9\times 10^9\times \dfrac{22\times 10^{-6}\times 46\times 10^{-6}}{(2.47\times 10^{-2})^2} \\\\F=14928.94\ N\\\\F=1.49\times 10^4\ N[/tex]
As the two charges have opposite sign, the force between them is attractive.
