1. Twopoint charges are separated by 6 cm. The attractive force betweenthem is 20 N. Find the force between them when they are separatedby 12 cm. (Why can you solve this problem without knowing themagnitudes of the charges?) <?xml:namespace prefix = o ns ="urn:schemas-microsoft-com:office:office" />
2. Explain thedifference between electrical potential and electricalpotential energy.
3. Whatis the voltage at the location of a 0.0001-coulomb charge that hasan electric potential energy of 0.5 joules?
