Question

Three charges are arranged as shown in the figure below. Find the magnitude and direction of the electronic force on the charge q = 4.74 nC at the origin. Letr_12 = 0.235 m.) magnitude N direction examine the diagram and determine which quadrant contains the angle of the net. counterclockwise from the x-axis. Three point charges are located at the corners of an equilateral triangle as in the figure below. Find the magnitude and direction of the net electric force on the 1.80 muC charge. (Let A = 1.80 muc 7.10 muc, and c = minus3.80 muC.) magnitude N

Explanation / Answer

Fx = kq1q2/r^2

direction is towards right side

Fy = kq1q2/r^2

direction towards downward

tan theta = tan^-1(Fy/Fx) = tan^-1(1.2798*10^-6)/(4.634857*10^-6) )

theta = 70.90 below horizontal
