Question

A square loop of sides a = 1 m is held normally in front of a point charge q = 1 C . The flux of the electric field through the shaded region is p 5 ​ × ε 0 ​ 1 ​ C Nm 2 ​ , where the value of p is _____.

TestHub · Accepted Answer

Total flux through square = ϵ 0 ​ q ​ ( 6 1 ​ ) Lets divide square is 8 equal parts. Flux is same for each part. ∴ Flux through shaded portion is 8 5 ​ (Total flux) = 8 5 ​ × ϵ 0 ​ q ​ 6 1 ​ = 48 5 ​ ϵ 0 ​ 1 ​ ∴ required Ans. is 48
