\(Q-1\)A capacitor has capacitance \(C\). Is this information sufficient to know what maximum charge the capacitor can contain ? If yes, what is this charge? If no, what other information is needed ?
\(Q-2\) The dielectric constant decreases if the temperature is increased . Explain this in terms of polarization of the material.
\(Q-3\) When dielectric slab is gradually inserted between the plates of an isolated parallel plate capacitor, the energy of the system decreases. What can you conclude about the force on the slab exerted by the electric field?
\(Q-4\) Suppose a charge \(+Q_1\) is given to the positive plate and charge \(-Q_2\) to the negative plate of a capacitor. What is the "charge on the capacitor"?
