The correct Answer is:
A, B, C, D
A-S, B-Q, C-R, D-P
(A) `E_c and E_F` are cancelled. `E_e and E_D` are at `60^@` to each other.
(B) `E_B and E_E` are cancelled `E_F and E_D` are at `120^@` to each other
(C ) `E_B and E_E` are cancelled similarly, `E_F and E_C` are cancelled
(D) `E_F and E_D` are at `120^@` to each other. So, their resultant is E in the direction of Hence, net electric field is 2E.
