Which of the following molecules is a polar molecule?

The excess of pressure, due to surface tension, on a spherical liquid drop of radius $R$ is proportional to

In a parallel plate air capacitor the distance between plates is reduced to one fourth and the space between them is filled with a dielectric medium of constant $2$. If the initial capacity of the capacitor is $4 \mathrm{\mu F}.$ Then its new capacity is

In a parallel plate capacitor, the capacity can be increased by decreasing

Four capacitors of equal capacity have an equivalent capacitance $C_1$ when connected in series and an equivalent capacitance $C_2$ when connected in parallel. The ratio $\frac{C_2}{C_1},$ is

Three condensers of capacities $C_1\text{, }{C}_2\text{,} C_3$ are connected in series with a source of e.m.f. $V$. The potentials across the three condensers are in the ratio of

The potential differences that must be applied across the parallel and series combination of $3$ identical capacitors is such that the energy stored in them becomes the same. The ratio of potential difference in parallel to series combination is

A series combination of $N_1$ each of capacity$C_1$ is charged to a potential difference $3\mathrm{V}$. Another parallel combination of $N_2$ (each of capacity $C_2$ is charged to a potential difference $V$. The total energy stored in both the combination is the same. The value of $C_1$ in terms of $C_2$ is
