During a lightning flash, there exists a potential difference of Vcloud - Vground = 1.4 x 109 V between a cloud and the ground. As a result, a charge of -30 C is transferred from the ground to the cloud. (a) How much work W ground-cloud is done on the charge by the electric force? (b) If the work done by the electric force were used to accelerate a 1100-kg automobile from rest, what would be its final speed? (c) If the work done by the electric force were converted into heat, how many kilograms of water at 0 °C could be heated to 100 °C? W ground-cloud- i Vf= m = i
