Answer:
38.1 N
Explanation:
The electrostatic force between two charged objects is given by:
[tex]F=k\frac{q_1 q_2}{r^2}[/tex]
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the separation between the two objects
In this problem, we have
[tex]q_1 = 0.000569 C\\q_2 = 0.00000186 C\\r = 0.5 m[/tex]
so, the electrostatic force is
[tex]F=(9\cdot 10^9 Nm^2 C^{-2})\frac{(0.000569 C)(0.00000186 C)}{(0.5 m)^2}=38.1 N[/tex]
