Okay say we know from magnetism.
E = F / q
F = KQq / R^2
Then we can say that.
E = KQq / (R^2 / q)
Then wouldn't we say
E = KQq * q / R^2
E = KQq^2 / R^2
Its just like saying.
5 / (1 / 2) = 5 * 2 / 1 = 10.
Why is it we cancel the q's instead of squaring them, because my textbook does that and ends up with this equation.
E = KQ / R^2
Because the answers are different. Thanks.
