Electric Potential Homework 1 1. During a lightning flash, -15 C of charge moves through a potential difference of 8.0 X 10"? V. Determine the change in electric potential energy of the field-charge system. 2. An electric sparkjumps from a person's finger to your nose. While passing through the air, the spark travels across a potential difference of 2.0 x 10"4 V and releases 3.0 x 10"-7 J of electric potential energy. What is the charge in coulombs, and how many electrons ow? 3. The equation below describes one or more physical processes. Solve the equation for the unknown and write a problem statement for which the equation is a satisfactory solution. 0 = (1/2) (1.0 x 10-2 kg) (6.0 m/s)2 + (2.0 x10'7 C)AV
