HELP I don't understand at all 1. The problem statement, all variables and given/known data Two positive point charges on the y-axis, each of which has a charge of 5.0 10-9 C, are located at y = +0.60 m and y = -0.60 m. Find the magnitude and direction of the resultant electric force acting on a charge of 7.6 10-9 C located at x = 0.80 m on the x-axis. 2. Relevant equations dont know 3. The attempt at a solution I have tired to many ways with to many numbers. My teacher hasn't taught these!
