1. The problem statement, all variables and given/known data A point charge q1 = -3.9 μC is located at the origin of a co-ordinate system. Another point charge q2 = 7.3 μC is located along the x-axis at a distance x2 = 7.8 cm from q1. 1) What is F12,x, the value of the x-component of the force that q1 exerts on q2? 2. Relevant equations F=(k*q1*q2)/r^2 3. The attempt at a solution [(-3.9*10^-6 C)*(7.8*10^-6 C)*(9*10^9 C)]/(0.078^2) m= -45 N but the answer is wrong I converted everything into metric units.
