Explanation:
Detailed explanation-1: -Question: Two charges separated by a distance of 1 meter except a 20 N force on each ether. If the charges are pulled as a 2 meter separation distance the force on each charge will be. 5 N.
Detailed explanation-2: -The force of repulsion of two +1.00 Coulomb charges held 1.00 meter apart is 9 billion Newton.
Detailed explanation-3: -F=kQ2r2=9×109×12×1(1000)2=9×103 N.
