Three charged particles are located at the corners of an equilateral triangle as shown in the figure below (let q = 1.40 pC, and L = 0.590 m). Calculate the total electric force on the 7.00-pC charge. 945 If you calculate the magnitude of the force that each charge exerts on the 7.00 µC charge, the net charge can then be found from the vector sum of those forces. N magnitude direction 316 • (counterclockwise from the +x axis) 7.00 µC 60.0° -4.00 µC

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.
