Polarisation — Prelims Questions

A parallel plate capacitor has a capacitance $C_0$ in air. When a dielectric slab of dielectric constant $K$ is introduced between the plates, completely filling the space, the electric field between the plates (assuming the capacitor is connected to a constant voltage source) will:

A parallel plate capacitor is charged and then disconnected from the battery. A dielectric slab of dielectric constant $K$ is then inserted between the plates. Which of the following quantities will decrease?

Which of the following molecules is an example of a non-polar molecule?

A dielectric material has an electric susceptibility $\chi_e = 3$. What is its dielectric constant $K$?

A parallel plate capacitor has plates of area $A$ and separation $d$. It is filled with a dielectric material of dielectric constant $K$. If the capacitor is connected to a battery of voltage $V$, what is the charge stored on the plates?

Which of the following statements about the polarisation of a dielectric material is INCORRECT?
