Question

Pls answer the question with explanation fast????

Answer 1

It will be zero if there would have been charges on each vertex.

but charge on A is missing that means there will be electric field on center due to D and other electric field vectors will cancel out each other.

so electric field on center is due to point charge q.

and that will be E= kq/l² along OA

so option "1" will be the right answer.

Answer 2

the correct answer is 1

hope it helped
