1. The problem statement, all variables and given/known data Three point charges lie along a straight line as shown in the figure below, where q1 = 6.36 µC, q2 = 1.56 µC, and q3 = -1.84 µC. The separation distances are d1 = 3.00 cm and d2 = 2.00 cm. Calculate the magnitude and direction of the net electric force on each of the charges. 2. Relevant equations 3. The attempt at a solution I did F of q1 on q2 is ((8.99x10^9) x .00000636 C x .00000156 C)/.0009 m=99.10576 N and F of q3 on q2 is ((8.99x10^9) x -.00000184 C x .00000156 C)/.0016 m=-286.72 N. Then for the Force on the middle charge I just added them together to get -187.8 N.
