Two questions.
1. a negative lightning bolt delivers a 15C charge from the ground to the BASE of a thunder cloud (Vpd = 5.0GV)
2. A positive lightning bolt delivers 20Ccharge from the Top of a thunder storm cloud to the ground (Vpd=30GV).
Both questions ask how much work is done to move the charge during the lightning strike. The question does give a distance but does that matter. using W=qVab I get my answer but BUT is one answer negative and one positive and why?
Thanks for the help in advance!
