A charge Q C is placed at the centre of a cube. The flux coming out from any one of its faces will be (in SI unit)
Options
- AQ 6 ₀ 10⁻³
- BQ 6 ₀ 10⁻⁶
- CQ ₀ 10⁻⁶
- D2 Q 3 ₀ 10⁻³
Correct answer
B. Q 6 ₀ 10⁻⁶
Step-by-step solution
According to Gauss law, total electric flux through a closed surface is _ net = q ₀ Total electric flux through the cube is _T= Q 10⁻⁶ ₀ Since charge is placed at the centre of the cube, therefore flux through each face is same. Hence, = 1 6 _T= 1 6 Q 10⁻⁶ ₀
