Q.

According to Gauss law of electrostatics, electric flux through a closed surface depends on            [2023]

1 the area of the surface  
2 the quantity of charges enclosed by the surface  
3 the shape of the surface  
4 the volume enclosed by the surface  

Ans.

(2)

For a closed surface net electric flux (Φ) depends upon the net charge enclosed. Mathematically Φ=qi0
