Two cylinders A and B fitted with piston contain equal amount of an ideal diatomic as at temperature ' T ' K . The piston of cylinder A is free to move while that of B is held fixed. The same amount of heat is given to the gas in each cylinder. If the rise temperature of the gas in A is ' $\mathrm{dT}_{\mathrm{A}}$ ', then the rise in temperature of the gas in cylinder B is $\left(\gamma=\frac{\mathrm{C}_{\mathrm{p}}}{\mathrm{C}_{\mathrm{v}}}\right)$

A
$2 \mathrm{dt}_{\mathrm{A}}$
B
$\frac{\mathrm{dT}_{\mathrm{A}}}{2}$
C
$\mathrm{\gamma d T_A}$
D
$\frac{\mathrm{dT}_A}{\gamma}$
