Draw electric field lines of simple charge distribution.
The picture of field lines was invented by Faraday to develop an way to visualizing electric fields around charged configurations. Faraday called them lines of force.
Figures show the field lines around some simple charge configurations. As mentioned earlier, the field lines are in $3$-dimensional space, though the figure shows them only in a plane.
Electric field lines for positive charge are shown in figure $(a)$. Electric field lines for negative charge are shown in figure $(b)$. Electric field lines for dipole are shown in figure $(c)$. For information :

$(b)$ Electric field lines for uniform electric fields :
$(c)$ Electric field lines on metallic sphere in uniform electric field :
Find out the surface charge density at the intersection of point $x =3\, m$ plane and $x$ -axis, in the region of uniform line charge of $8\, nC / m$ lying along the $z$ -axis in free space.
The electric flux for Gaussian surface A that enclose the charged particles in free space is (given $q_1$ = $-14\, nC$, $q_2$ = $78.85\, nC$, $q_3$ = $-56 \,nC$)
In figure a point charge $+Q_1$ is at the centre of an imaginary spherical surface and another point charge $+Q_2$ is outside it. Point $P$ is on the surface of the sphere. Let ${\Phi _s}$be the net electric flux through the sphere and ${\vec E_p}$ be the electric field at point $P$ on the sphere. Which of the following statements is $TRUE$ ?
A few electric field lines for a system of two charges $Q_1$ and $Q_2$ fixed at two different points on the $x$ -axis are shown in the figure. These lines suggest that:-
A long cylindrical volume contains a uniformly distributed charge of density $\rho$. The radius of cylindrical volume is $R$. A charge particle $(q)$ revolves around the cylinder in a circular path. The kinetic of the particle is
