A charge 'Q' C is placed at the centre of a cube. The flux through one face and two opposite faces of the cube is respectively
Options
- AQ 6 ₀ Vm , Q 3 ₀ Vm
- BQ 12 ₀ Vm , Q ₀ Vm
- CQ 6 ₀ Vm , Q 2 ₀ Vm
- DQ 12 ₀ Vm , Q 3 ₀ Vm
Correct answer
A. Q 6 ₀ Vm , Q 3 ₀ Vm
Step-by-step solution
By using Gauss's Law. It is given as = E d s = q ₀ Now, the flux passing through all the six surfaces would be =6 = q ₀ And the flux passing through each surface would be = q 6 ₀
