Akash Anand @ShreyaWhy B is not correct ??

Shreya Sharma I think B will be correct if we assume q1 to be at infinity from q2. But it is at a distance of 'd' so it will affect the space around q2 a little bit. Is it right, sir?

Akash Anand But as much as you move closer to q2 then the term of field will increase very rapidly i.e tends to infinity, so in that case we can neglect the effect due to q1 as it is a finite field. B will also be correct.

field for q₂ = k(Qr²) for a unit negative charge..
so as "r" tends to zero, means we go very close to q₂, the field tends to infinity..
so maybe..
