Practice Tamil Nadu HSC (Class 12) Electrostatics in the app →The fact that any observable charge is an integral multiple of the elementary charge $e$ is known asThe SI unit of electric field intensity isWhich charge configuration produces a uniform electric field?Electric field lines can never intersect each other becauseThe electric dipole moment of a dipole pointsWhen placed in a uniform external electric field, an electric dipole experiencesThe electrostatic potential at a point due to a point charge $q$ at distance $r$ isThe capacitance of a capacitor is defined asTwo objects rubbed together acquire a charge of $50\ nC$ each. The number of electrons transferred is aboutTwo point charges repel each other with force $F$. If the distance between them is doubled while the charges aAn electric dipole of length $1\ cm$ aligned at $30^\circ$ to a field $2\times10^{5}\ N\,C^{-1}$ experiences aPoints A and B are at potentials $+7\ V$ and $-4\ V$. The work done in moving 50 electrons from A to B isIf the voltage across a capacitor is increased from $V$ to $2V$, thenThe relation between the electric field and the electrostatic potential isAn electric field $\vec{E} = 10x\,\hat{i}$ (SI units) exists in a region. The potential difference $V_O - V_A$An equipotential surface is one on whichTwo identical conducting spheres carry positive charges $q_1$ and $q_2$ ($q_1 \ne q_2$) and repel with force $Two metal spheres of radii $1\ cm$ and $3\ cm$ carry charges $-1\times10^{-2}\ C$ and $+5\times10^{-2}\ C$. WhA parallel-plate capacitor has capacitance $C$. If BOTH the plate area and the plate separation are doubled, tBy Gauss's law, the total electric flux through a closed surface enclosing a net charge $Q_{enc}$ isThe energy stored in a capacitor of capacitance $C$ charged to voltage $V$ (holding charge $Q$) isA charge $q$ is enclosed by a closed surface immersed in a medium of relative permittivity (dielectric constanOn the axial line of a short dipole the electric field is $E_a$, and on the equatorial line at the same distan
