12 A cylindrical box is moving with a constant velocity along its axis in a chamber filled with an ideal gas Velocity of the cylinder is so small that it does not produce any turbulence in the gas If absolute temperature of the gas is doubled in what way must speed of the cylinder be changed to keep the drag force unchanged a It must be made 0 354 times of its previous value b It must be reduced to half of its previous value c It must be made 0 707 times of its previous value d Drag force does not depend on the temperature of the gas
