Dipole having dipole moment $4\,C-m$ is placed on origin along $x-$ axis. Point charge of $8\,\mu C$ is fixed at $(4, 0, 0)$ . Now dipole is rotated by an angle of $\frac{\pi }{2}$ . Find the work done (in $mJ$ ) in rotating the dipole.......$mJ$
How will the voltage $(V)$ between the two plates of a parallel plate capacitor depend on the distance $(d)$ between the plates, if the charge on the capacitor remains the same?
The plates of a parallel plate capacitor are charged up to $100\, volt$. A $2\, mm$ thick plate is inserted between the plates, then to maintain the same potential difference, the distance between the capacitor plates is increased by $1.6\, mm$. The dielectric constant of the plate is
All the six capacitors shown in the circuit are identical. Each can withstand maximum $200\, volt$ between its terminals. The maximum voltage that can be applied safely between $A$ and $B$ is.....$V$

Four very large metal plates are given the charges as shown in figure. The middle two are then connected through a wire. Find the charge that will flow through the wire
The adjacent diagram shows a charge $+Q$ held on an insulating support $S$ and enclosed by a hollow spherical conductor. $O$ represents the centre of the spherical conductor. and $P$ is a point such that $OP = x $ and $SP = r$ . The electric field at point $P$ will be
