Question

Your answer is partially correct. Try again. Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.100 N when their center-to-center separation is 39.6 cm. The spheres are then connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electrostatic force of 0.0493 N. Of the initial charges on the spheres, with a positive net charge, what was the negative charge in coulombs on one of them and the positive charge in coulombs on the other? Number Units Number Units

Explanation / Answer

initial charges be q1 , q2 final charges = Q ,Q q1 + q2 = Q * 2 9*10^9 * q1 * q2 / 0.396^2 = -0.1 q1 * q2 = -1.742*10^-12 9*10^9 * Q^2/ 0.396^2 = 0.493 Q = 2.93*10^-6 columbs q1 +q2 = 5.86*10^-6 negative charge = -0.56 * 10^-6 positive charge = 6.14*10^-6
