Hi aspirant!!

As the net electric field at the centre is zero. I have given below there is explanation

Given Q is the total charge. Let R be the radius of the circular loop

Because of the circular loop the net electric field = 0

Therefore the “net electric field” due to the remaining loop= the charge on dL. hence charge dL

=Q/2πRdL

The charge dL due to the electric field is the electric field due to the center of the circular loop.

Electric field: It is a region around the charged particles. It can exert the force on the other charges in the field. The charges can attract or repel the forces.

the “net charge” is zero then the object is said to be in the “neutral state”.

I hope your doubt is clear .

Thank you !!!
