$A$ metallic sphere is kept in between two oppositely charged plates. The most appropriate representation of the field lines is

Which of the following represents the correct path of electric field lines when a metallic sphere is placed in a uniform electric field?

$A$ $6 \mu C$ charge is placed at the centre of a cube. What will be the electric flux through each face of the cube? (Take $\frac{1}{4 \pi \epsilon_0} = 9 \times 10^9 \ Nm^2 C^{-2}$)

$A$ charge $q$ is placed at the centre of the open end of a cylindrical vessel. The flux of the electric field through the surface of the vessel is:

What can be said about the electric charge if the electric flux associated with a closed loop (surface) is zero?

Three positive charges of equal value $q$ are placed at the vertices of an equilateral triangle. The resulting lines of force should be sketched as in:
