1.	Figure shows three point charges, +2q, -q and +3q. Two charges +2q and -q are enclosed within a surface ‘S’. What is the electric flux due to this configuration through the surface ‘S’?
Answer» Electric flux ϕ = 1/ε₀ x (net charge enclosed by surface S) = 1/ε₀ x (2q - q) = q/ε₀

Figure shows three point charges, +2q, -q and +3q. Two charges +2q and -q are enclosed within a surface ‘S’. What is the electric flux due to this configuration through the surface ‘S’?

Answer»

Electric flux ϕ = 1/ε₀ x (net charge enclosed by surface S)

= 1/ε₀ x (2q - q) = q/ε₀
