In a thundercloud there may be an electric charge of 55 C near the top of the cloud and −55 C near the bottom of the cloud. If these charges are separated by about 4 km, what is the magnitude of the elec- tric force between these two sets of charges? The value of the electric force constant is 8.98755 × 109 N · m2/C2. Unit 7 HW 1 – mclain – (3410-4) 1 Answer in units of N.
