1. The problem statement, all variables and given/known data Charges q1, q2, q3 are placed in a right triangle. Charges are given, distance between charges is given. Find the electrical field strength at point "A" which is in the middle of the hypotenuse. Which equations and how would I figure that out knowing that I have to give magnitude and direction? 2. Relevant equations E=kq/r^2 --> ?not sure 3. The attempt at a solution I drew out a diagram and found all the angle, after that I am completely lost.
