Electric force angles problem :( 1. The problem statement, all variables and given/known data Three positive particles of charges 11.0 µC are located at the corners of an equilateral triangle of side d = 14.0 cm (Fig. 16-38). Calculate the magnitude and direction of the net force on each particle. Fig. 16-38 2. Relevant equations F = KQ_1Q_2/r^2 3. The attempt at a solution F = KQ_1Q_2/r^2 F = (9X10^9)(1.1X10^-5)^2/.14^2 F = 55.561 N for all points - Q1, Q2, and Q3 (correct) Q1 angle = 90 degrees (correct) Q2 angle = ? Q3 angle = ? I need to find the directional angle for particles Q2 and Q3 - I am unsure how to find these. I was thinking I might have to draw a triangle? Thanks, Bensky
It's an equilateral triangle. [tex]\angle Q_1=\angle Q_2=\angle Q_3[/tex] [tex]\angle Q_1+\angle Q_2+\angle Q_3=180[/tex]
I'm not looking for the interior angles, I'm looking for the angle of direction of force on Q2 and Q3.
