Question description

Two small identical conducting balls start with different amounts of charge on them. Initially, when they are separated by 70.0 cm (this is the center-to-center distance), one ball exerts an attractive force of 2.50 N on the second ball. The balls are then touched together briefly (charge is conserved in this process), and then again separated by 70.0 cm. Now both balls have a positive charge, and the force that one ball exerts on the other is a repulsive force of 1.20 N. For this problem, use k = 9.0 [img src="http://www.webassign.net/images/multiply.gif"> 109 N m2 / C2,70.0 cm.(a) After the two balls have been touched together, what is the charge on each ball?(b) Before they were touched together, one ball had a positive charge. How much charge did that ball (c) Before they were touched together, one ball had a negative charge. How much charge did that ball have? (Don't forget to include the minus sign!)
