Explanation & Answer
Thank you for the opportunity to help you with your question!
The attractive electrostatic force between the point charges 8.76×10−6C and Q has a magnitude of 0.275 N when the separation between the charges is 9.20 m F = kqQ/r^2 = 0.275
Q = 0.275*9.2^2/(9x10^9 *8.75x10^-6)
=2.96 x10^-4 C
