Question 1:

Gauss's Law relates the electric flux through a closed surface to:

Explanation: Gauss's Law relates the electric flux through a closed surface to the charge enclosed by the surface. It states that the electric flux is proportional to the charge enclosed divided by the permittivity of the medium. Mathematically, Φ = (q_enclosed) / ε0.

Question 2:

The unit of electric flux is:

Explanation: The unit of electric flux is Newton-meter squared per Coulomb (N·m²/C), also known as the Volt-meter (V·m).

Question 3:

When an electric field line crosses a closed Gaussian surface, the electric flux through that surface is:

Explanation: When an electric field line crosses a closed Gaussian surface, the electric flux through that surface is zero. This is because the electric field lines both enter and exit the surface, resulting in a cancellation of flux.

Question 4:

The flux of an electric field through a closed surface is maximum when:

Explanation: The flux of an electric field through a closed surface is maximum when the surface is perpendicular to the electric field lines. In this case, all the electric field lines pass through the surface, resulting in maximum flux.

Question 5:

If the electric flux through a closed surface is zero, it implies:

Explanation: If the electric flux through a closed surface is zero, it implies that the net charge enclosed by the surface is zero. This means that the sum of positive and negative charges within the surface cancels out, resulting in zero net charge.
