Consider a system of three charges `q/3, q/3 and –2a/3` placed at points A, B and C respectively as shown in the figure. It the radius of the circle is R and `/_CAB = 60^o` then the electric field at centre 0 is ........
Options:
(a) `q/( 8π epsilon_oR^2)`
(b) `q^2/( 54π epsilon_oR^2)`
(c) `q/( 6π epsilon_oR^2)`
(d) 0)
