Question

When a point charge placed at corner of cube the total flux through cube is phi. What is the flux from each face of cube

Answer 1

Answer:

(4)

Explanation:

because Φ=q/ε24 at the corner (1)

now when this same charge placed at the centre of cube

then,

Φ' = q/ε6 ---(2)

on comparing 2 & 1, we get on division 2÷1

Φ'= Φ/4
