Two identical conducting spheres, fixed in place, attract each other with an electrostatic force of 0.125 N when their center-to-center separation is 68.7 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 0.0520 N. Of the initial charges on the spheres, with a 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 smaller magnitude.) (a) Number Units (b) Number Units

A 0.00230 kg air-inflated balloon is given an excess negative charge q1 = -4.00 x 10^-8 C by rubbing it with a blanket. Then, a charged rod held above the balloon at a distance of d = 0.0760 m makes the balloon float in place.  How much charge q2 does the rod have?

Two balloons (m = 0.022 kg) are separated by a distance of d = 12 m. They are released from rest and observed to have an instantaneous acceleration of a = 1.1 m/s2 toward each other at the moment they are released. Assume the two balloons are point charges and have equal but opposite charges. Part (a)  Calculate the magnitude of the charge on each balloon in C.  Part (b)  How many electrons are responsible for the charge, N?

The drawings show three charges that have the same magnitude but different signs. In all cases the distance d between the charges is the same. The magnitude of the charges is |q|= 7.3 µC, and the distance between them is d = 4.6 mm. Determine the magnitude of the net force on charge 2 for each of the three drawings
