As in the problem below if you do not know how to integrate you must look up the formula. It looks like:
U = potential energy = k Q1 Q2/R
Two identical +9.5uF point charges are initially 3.5cm from each other.
If they are released at the same instant from rest, how fast will each be moving when they are very far away from each other? Assume they have identical masses of 2.0mg (P.s. I am not in calculus) so the algebraic way would be great!
