Question

A very small sphere having a charge q , uniformly distributed throughout its volume, is placed at the vertex of a cube of side a . The electric flux through the cube is, q ε 0, q 3 ε 0, q 6 ε 0, q 8 ε 0

MARKS App · Accepted Answer

If charge q is placed at a corner of cube, it will be divided into 8 such cubes. Therefore, electric flux through the cube is ϕ ′ = 1 8 q ε 0
