Three charges each of are placed at the comers of an equilateral triangle. If the force any two charges be`F`,then the net force on each charge is.

Explanation

Force on A,
Due to B, `" " F_1 = (1)/(4 pi in _0) ((10^(-6))^(2))/((3xx 10 ^(-2))^(2))`
Due to C, ` " " F_2= (1)/(4piin_0) ((10^(-6))^(2))/((3xx 10 ^(-2))^(2))`

Resultant force on charge at A,
` F = (9xx 10 ^(9) xx (10^(-6))^(2))/((3xx 10^(-2))^(2)) xx sqrt3 = 10 sqrt3 N`
