A parallel plate capacitor is charged to a certain potential and the charging battery is then disconnected. Now, if the plates of the capacitor are moved apart then:
The stored energy of the capacitor increases
Charge on the capacitor increases
Voltage of the capacitor decreases
The capacitance increases
The energy density $u$ is plotted against the distance $r$ from the centre of a spherical charge distribution on a $log$-$log$ scale. The slope of obtianed straight line is :
A capacitor of capacity $C$ has charge $Q$ and stored energy is $W$. If the charge is increased to $2Q$, the stored energy will be
A battery does $200 \,J$ of work in charging a capacitor. The energy stored in the capacitor is ......... $J$
A $10\,pF$ capacitor is connected to a $50 \,V$ battery. How much electrostatic energy is stored in the capacitor
The energy stored in a condenser is in the form of
