Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions. Equate the gravitational force to the electrostatic force: <span>KC²/D² = Gm²/D² → C = m√[G/K] = 7.6√[6.67E-11/9E9] = 6.54E-10 coulombs </span> <span>Number of electrons N = 6.24E18*C = 4.083E9 electrons</span>
