Answer 1

Answer:

Explanation:

a wire of length L and linear charge density is λ = Kx 

 we know,

     linear charge density means charge per unit length.

so, we can say, λ = dQ/dx

⇒ dQ = λ.dx 

⇒ ∫dQ = ∫Kx.dx    [∵  λ = Kx ]

⇒ 

⇒ Q = KL²/2

 now, according to Gaussian theorem,

  Ф = Q/ε₀

 here, Ф is electric flux, Q is net charge inclosed in Gaussian surface and ε₀ is permitivity of medium [vaccum]

so, Ф = KL²/2ε₀

flux through s1=Q/ε₀

flux through s2=[Q+[1/2]kl^2]/ε₀
