[SOLVED] Electric force and charge 1. The problem statement, all variables and given/known data A positive charge of 2.90 μC is at rest at the origin. An electric force of 65.5 x 10-6 N acts on the charge as shown in the figure below. What is the x-component of the electric field at the origin? 2. Relevant equations F=kQ/r^2 E=kq1q2/r^2 3. The attempt at a solution I subbed the charge and force into F=k Q/r^2 and solved for r thinking I could dos somehting with it but it is a hugeeee number so I doubt im doing it right.
