Four identical conducting spheres A, B, C and D have net charges of -8.0 C,-6.0 C,-4.0 C and +80 C,respectively. Which (2, 3 or 4) of these spheres must be connected together (by a short and thin wire) to produce: (a) A system of balls in which each ball has a charge of-2.0 C ? (b) A system of balls in which each ball has a charge of -2.5 c1 (c) What sequence of connections will produce 2 spheres, each with -3.0 C?

    Two conducting spheres have identical radii. Initially they have charges of opposite sign and unequal magnitudes with the magnitude of the positive charge larger than the magnitude of the negative charge. They attract each other with a force of 0.27 N when separated by 0.4 m. The spheres are suddenly connected by a thin conducting wire, which is then removed. Now the spheres repel each other with a force of 0.045 N. A.) What is the magnitude of the positive...
