10 cm from both ends means symmetrical and distance from center

Now since its symmetric so the component along the wire length will be cancelled so the only component that remains is perpendicular to plane.

Where l is length of wire.
Thanks & Regards

Dear Student,
Please find below the solution to your problem.

10 cm from both ends means symmetrical and distance from center
z = √3/2*10
Now since its symmetric so the component along the wire length will be cancelled so the only component that remains is perpendicular to plane.
Eperpendicular = 2klλ / (z(z^2 + (l/2)^2))
Where l is length of wire.

Thanks and Regards
