Question

Q.25 If the flux through a cube due to a point charge is K. Then what will be the
flux through a square due to same charge of same side length?​

Answer 1

Answer:

In these faces , electric field due at Q will be in the plane of faces , electric field due to Q willbe in the plane of face and area is perpendicular to face hence fluxϕ′=EScos90∘=0. The flux through these threefaces is zero
