I missed the material for these couple of problems. If someone could help explain how to solve them I would much appreciate it. 1.) A charge of +2 x 10^-6 C is 20cm from a charge of -3 x 10^-6 C. Find the magnitude and direction of the force on each charge. 2.) A 120-V electric coffeepot draws a current of 0.6 A. What is the resistance of its heating element?
