pls thums up if understand the method.a) Each charge particle experiences 3 fous due to other 3 charges.So total electrieal &Al forer =3xx4=12b) In F ig (1)F_(B)=F_(D)*=> Recultent of F_(D) and F_(B) at C will be celong FA_(1)A_(1) shown in figure vector sum of all forces on charge particles will be zero(2) From Neuton's thind law of action - Reaction we can say that vector sum of all electrostaki) foreer will be zero{:[ vec(F)_(R)= vec(F)_(B)+ vec(F)_(D)+ vec(F ...
