A point charge q is kept at the corner of a cube. What is the flux through each side of the cube?
Answer & explanation
Correct answer: option 3
The correct answer is Option 3: q/24εo
Total flux =q/εo
8 cubes share → flux per cube =q/8εo
3 faces lie in the plane of the charge → zero flux
Remaining 3 faces share equally
Flux per face= q/24εo
