If an electric field is given by $10 \hat{i}+3 \hat{j}+4 \hat{k}$, calculate the electric flux through a surface of area $10$ units lying in $y z$ plane ....... units

A square surface of side $L$ meter in the plane of the paper is placed in a uniform electric field $E(volt/m)$ acting along the same plane at an angle $\theta$ with the horizontal side of the square as shown in figure.The electric flux linked to the surface, in units of $volt \;m $

Sketch the electric field lines for a uniformly charged hollow cylinder shown in figure.

A uniformly charged conducting sphere of $2.4\; m$ diameter has a surface charge density of $80.0\; \mu \,C/m^2$.

$(a)$ Find the charge on the sphere.

$(b)$ What is the total electric flux leaving the surface of the sphere?

A point charge $q$ is placed on the centre of a hemispherical surface as shown in figure.The net flux of electric fietd tnroug the hemi-spherical surface is closest to

What is the flux through a cube of side $a$ if a point charge of $q$ is at one of its comer?
