During a lightning ash, there exists a potential difference of Vdoud - ngund = 2.8 x 109 V between a cloud and the ground. As a result, a charge of -16 C is transferred from the ground to the cloud. (3) How much work ngund_doud is done on the charge by the electric force? (b) If the work clone by the electric force were used to accelerate a 1100kg automobile from rest, what would be its nal 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? Wground -cloud = I 6 Vr= '"= I 4} (b
