A uniformly charged cube of side one cm having surface charge density of $8.85\ \mu C\text{ cm}^{-2}$ is placed inside a hollow metal sphere. The total flux emerging out of the sphere in $\text{Nm}^{2}\text{C}^{-1}$ is ($\epsilon_{0}=8.85\times 10^{-12}\text{C}^{2}\text{N}^{-1}\text{m}^{-2}$)

The inward and outward electric flux from a closed surface are \( 6\times10^4 \,\text{Nm}^2\text{C}^{-1} \) and \( 3\times10^4 \,\text{Nm}^2\text{C}^{-1} \). Then the net charge (in coulomb) inside the closed surface is

The electric flux (in SI units) through any face of a cube due to a positive charge \(Q\) situated at the centre of the cube is

A charge $Q$ placed at the center of a metallic spherical shell with inner and outer radii $R_1$ and $R_2$ respectively. The normal component of the electric field at any point on the Gaussian surface with radius between $R_1$ and $R_2$ will be

A sphere of radius $R$ has a uniform volume charge density $\rho$. The magnitude of electric field at a distance $r$ from the center of the sphere, where $r > R$, is

A cylinder of radius $r$ and length $\ell$ is placed in a uniform electric field $E$ parallel to its axis. The total flux over curved surface area is
