Question

Please can someone answer this with solutions? Thank you very much

Three positive point charges of 3.0 µC, 6.0 µC, and 2.0 µC, respectively, are arranged in a triangular pattern, as shown in the figure below. Find the magnitude and direction of the electric force acting on the 6.0 µC charge.

Answer 1

$F=F_1+F_2\cos\phi-F_3\sin \phi=9.7\cdot 10^{-8}~N,$

$\theta=\arctan \frac{F_y}{F_x}=-11.4°.$
