Question

Chapter 21, Problem 009 d in place, attract each other with an electrostatic force of 0.138 N when their center-to-center separation is 53.3 cm. The spheres are then ostatic force of 0.0363 N. of the initial charges on the spheres, with a connected by a thin conducting wire. When the wire is removed, the spheres repel each other with an electr positive net charge, what was (a) the negative charge on one of them and (b) the positive charge on the other? (Assume the negative charge has smaile magnitude.) (a) Number (b) Number Units Units

Answer 1

Let be the i on using couwuubs la ane )-E9A ^ 0.138 χ (0.533)2 Since, it įs told , chances ottr och coch ơthen . Sa , o*e of them is pasiti vc No wo sphoesare joied by wine.
