Three charged particles are located at the corners of an equilateral triangle as shown in the figure below (let q = 2.20 µC, and L = 0.530 m). Calculate the total electric force on the 7.00-µC charge.
Magnitude: N
Direction: ° (counterclockwise from the +x axis)
Three charged particles lie in the xy coordinate plane at the vertices of an equilateral triangle with side length L. The positive charge q is at the origin. A charge of 7.00 µC is in the first quadrant, along a line 60.0° counterclockwise from the positive x-axis. A charge of -4.00 µC is at (L, 0).
