Question

A charge Qµc is placed at the centre of a cube the flux coming from any surface will be.

Options

• `Q/(6E_0) xx 10^-6`

• `Q/(6E_0) xx 10^-3`

• `Q/(24E_0)`

• `Q/(8E_0)`

Answer 1

`Q/(6E_0) xx 10^-6`

Explanation:

According to gauss's theorem, total flux coming from six faces of cube:

`phi = (Q xx 10^-6)/E_0`

∴ The flux from each face `phi = (Q xx 10^-6)/(6E_0)`
