The magnitude of the electrostatic force between two charge
:
F = kQ1*q2/r^2 ---> Q1 = Q2 =Q
= k Q^2/r^2
= 9 x 10^9 * (6 x 10^-6)^2/9 x 10^-4 =360 N
Between the different forces acting on each other is an angle of
60°. Let the negative charge be at C.
Then the net force acting on C by the positive charges at A and B
is
FC = √(360^2 + 360^2 +2*360*360*cos(60°)) (= length of long
diagonal in a parallelogram)
FC = 623.53 N
and
FA = FB = √(360^2 + 360^2 - 2*360^2*cos(60°) (= length of short
diagonal in a parallelogram)
= 360 N
