A parallel plate condenser with oil between the plates (dielectric constant of oil K = 2) has a capacitance C. If the oil is removed, then capacitance of the capacitor becomes
A tank containing a liquid has turns of wire wrapped around it, causing it to act as an inductor. The liquid content of the tank can be measured by using its inductance to determine the height of the liquid level in the tank. The inductance of the tank changes from a value of $L_0$ corresponding to a relative permeability of $1$ when the tank is empty to value $L_f$ corresponding to a relative permeability $X_m$ (relative permeability of liquid) when the tank is full. The appropriate electronic circuit can determine the inductance correct upto $5$ significant figures and thus the effective relative permeability of the combined air and liquid within the rectangular has height $D$. The height of the liquid level in the tank is d . Ignore the fringing effects. Assume tank is fitted with $H _{ g } X _{ Hg }=2.9 \times 10^5$. Express d as a function of $L$, inductance corresponding to a certain liquid height $LO,Lf$ and $D$.
