Q.
Three charges each of + 1$\mu C$ are placed at the corners of an equilateral triangle. If the force between any two charges be F, then the net force on either charge will be
A) $\sqrt{2}\ F$
B) $F\sqrt{3}\ $
C) 2F
D) 3F
Explanation
(b) Angle between two forces due to individual charges is equal to 60$^{0}$
$\therefore\ \ R = \sqrt{F^{2} + F^{2} + 2F\ F\cos 60^{0}} = \ F\sqrt{3}$
