1. The problem statement, all variables and given/known data The Electric field between a cloud and the ground is 1.0X10^6 N/C. If 35C of charge is transfered to the ground (lightning bolt) over a distance of 2.3km, what is the voltage of the cloud. 2. Relevant equations q=mg/E? 3. The attempt at a solution I dont have the best high school physics teacher. He doesnt just do the problem, he makes us actually have to think on our own which is amazingly hard. I dont know where to start on this. Help if you have time to waste or procrastinating.
