Given the value of Rydberg constant is $10^7{\text{m}}^{-1}$, the wave number of the last line of the Balmer series in hydrogen spectrum will be:

The ratio of escape velocity at earth $(v_e)$ to the escape velocity at a planet $(v_p)$ whose radius and mean density are twice as that of earth is:

A long solenoid has 1000 turns. When a current of $4\text{A}$ flows through it the magnetic flux linked with each turn of the solenoid is $4\times 10^{-3}\text{Wb}$. The self-inductance of the solenoid is:

A car is negotiating a curved road of radius $R$. The road is banked at an angle $\theta$. The coefficient of friction between the tyres of the car and the road is ${\mu }_s$. The maximum safe velocity on this road is:

The magnetic susceptibility is negative for:
