Three Charges 2q, -q and -q Lie at Vertices of a Triangle. The Value of E and V at Centroid of Triangle Will Be - Bzziii

Three Charges 2q, -q and -q lie at vertices of a triangle. The value of E and V at centroid of triangle will be- 

(i) E#0 and V#0 
(ii) E=0 and V=0 
(iii) E#0 and V=0 
(iv) E=0 and V#0 

(iii) E#0 and V=0 

Explanation:

Three Charges 2q, -q and -q lie at vertices of a triangle. The value of E and V at centroid of triangle will be E#0 and V=0

Net E F I at G ≠  O

Net Potential at G,

V = `\frac{"K2Q"}{"r"}`-`\frac{"KQ"}{"r"}`-`\frac{"KQ"}{"r"}` = 0
