Hey.. thanks for the video, I have a question hoping you'll answer (Michael Van Bizen has answered to one of my comments and say im right haha..) okay.. Why would they give us the d ? if theres no use, and second why would you use this formula and not " flux = (E)(dA).. dA const which is d^2... and E = r = (d/2)^2 .... waiting for your answer, thanks !
