Young’s double slit experiment is first performed in air and then in a medium other than air. It is found that $8^{\text{th}}$ bright fringe in the medium lies where $5^{\text{th}}$ dark fringe lies in air. The refractive index of the medium is nearly:

In a common emitter transistor amplifier the audio signal voltage across the collector is $3\text{V}$. The resistance of collector is $3\text{k}\Omega$. If current gain is $100$ and the base resistance is $2\text{k}\Omega$, the voltage and power gain of the amplifier is:

An arrangement of three parallel straight wires A, B, and C (carrying current $I$ in same direction) are placed perpendicular to the plane of paper. A and C are at a distance $d$ from B, and the angle $\angle ABC=90^{\circ }$. Magnitude of force per unit length on the middle wire ‘B’ is:

The de-Broglie wavelength of a neutron in thermal equilibrium with heavy water at a temperature $T$ (Kelvin) and mass $m$, is:
