Embibe Experts Solutions for Exercise 1: EXERCISE

An electric dipole consists of two opposite charges each of magnitude $2\mu \mathrm{C}$ separated by a distance $1 \mathrm{cm}$. The dipole is placed in an external field of ${10}^3 \mathrm{N}\hspace{0.17em}{\mathrm{C}}^{-1}$. The maximum torque on the dipole is

A point $B$ lies on the perpendicular bisector of an electric dipole of dipole moment $\overrightarrow{p}$. The distance of $B$ from the dipole is $r$ ($r$ is much larger than the size of the dipole). The electric intensity at $B$ is proportional to

The electric field due to a point charge at a distance $6 \mathrm{m}$ from it is $630 \mathrm{N}\hspace{0.17em}{\mathrm{C}}^{-1}$. The magnitude of the charge is

The net flux passing through a closed surface enclosing unit charge is

A uniformly charged conducting sphere is having radius $1 \mathrm{m}$ and surface charge density $20 \mathrm{C} {\mathrm{m}}^{-2}$. The total flux leaving the Gaussian surface enclosing the sphere is

$S_1,S_2,S_3$ are three concentric spherical shells, as shown in figure. $S_1$ and $S_2$ have charge $4 Q$ and $8 Q$ respectively, whereas $S_3$ is uncharged. Find the ratio of the flux passing through $S_1$ to that through $S_3$

If $r$ is distance measured from centre of a charged shell and $R$ is its radius, then the graph which may correctly represent variation of electric field $\left(E\right)$ is

The flux through the hemispherical surface in the figure shown below is
