Two bar magnets '$$\mathrm{P}$$' and '$$\mathrm{Q}$$' are kept in uniform magnetic field '$$\mathrm{B}$$' with magnetic moments '$$\mathrm{M_P}$$' and '$$\mathrm{M_Q}$$' respectively. Magnet 'P' is oscillating with frequency twice that of magnet 'Q'. If the moment of inertia of the magnet 'P' is twice that of magnet 'Q' then

$$\mathrm{M}_{\mathrm{Q}}=2 \mathrm{M}_{\mathrm{P}}$$

$$\mathrm{M_P=2 M_Q}$$

$$\mathrm{M}_{\mathrm{P}}=8 \mathrm{M}_Q$$

$$\mathrm{M}_{\mathrm{Q}}=8 \mathrm{MP}_{\mathrm{P}}$$

Which one of the following is NOT a correct expression for an ideal gas?

[$$\mathrm{C_p}=$$ Molar specific heat of a gas at constant pressure,

$$\mathrm{C_v}=$$ Molar specific heat of a gas at constant volume,

$$\mathrm{Y}=$$ Ratio of two specific heats of a gas,

$$\mathrm{R}=$$ Universal gas constant]

$$C_v=C_p+R$$

$$R=C_v(\gamma-1)$$

$$\frac{C_v}{\mathrm{C}_{\mathrm{p}}}=\frac{1}{\gamma}$$

$$R=\frac{C_{\mathrm{p}}(\gamma-1)}{\gamma}$$
