**Question:**

An electric dipole has a fixed dipole moment $p$, which makes angle $\theta$ with respect to $x$-axis. When subjected to an electric field $\overrightarrow{E_{1}}=E \hat{i}$, it experiences a torque $\vec{T}_{1}=\tau \hat{i}$. When subjected to another electric field $\overrightarrow{E_{2}}=\sqrt{3 E_{1}} \hat{j}$ it experiences torque $\overrightarrow{T_{2}}=-\vec{T}_{1}$. The angle $\theta$ is :

Three charges $+Q, q,+Q$ are placed respectively, at distance, $\mathrm{d} / 2$ and d from the origin, on the $x$-axis. If the net force experienced by $+Q$, placed at $x=0$, is zero, then value of $\mathrm{q}$ is:

Charge is distributed within a sphere of radius $R$ with a volume charge density $\mathrm{p}(\mathrm{r})=\frac{\mathrm{A}}{\mathrm{r}^{2}} \mathrm{e}^{-2 \mathrm{r} / \mathrm{a}}$ where $\mathrm{A}$ and $\mathrm{a}$ are constants.

Two identical conducting spheres $A$ and $B$, carry equal charge. They are separated by a distance much larger than their diameter, and the force between them is F. A third identical conducting sphere, $\mathrm{C}$, is uncharged. Sphere $\mathrm{C}$ is first touched to $A$, then to $B$, and then removed. As a result, the force between $A$ and $B$ would be equal to

Two balls of same mass and carrying equal charge are hung from a fixed support of length $l$. At electrostatic equilibrium, assuming that angles made by each thread is small, the separation, $x$ between the balls is proportional to :

Two identical charged spheres suspended from a common point by two massless strings of length $l$ are initially a distance $d(d<<l)$ apart because of their mutual repulsion. The charge begins to leak from both the spheres at a constant rate. As a result charges approach each other with a velocity $v$. Then as a function of distance $x$ between them,

A charge $Q$ is placed at each of the opposite corners of a square. A charge $q$ is placed at each of the other two corners. If the net electrical force on $Q$ is zero, then $Q / q$ equals:

Two spherical conductors $B$ and $C$ having equal radii and carrying equal charges on them repel each other with a force $F$ when kept apart at some distance. A third spherical conductor having same radius as that $B$ but uncharged is brought in contact with $B$, then brought in contact with $C$ and finally removed away from both.
