A horizontal tube of length l closed at both ends contains an ideal gas of molecular weight M. The tube is rotated at a constant angular velocity m about a vertical axis passing through an end, Assuming the temperature to be uniform and constant, pressure P at the free end is___ (pressure at fixed end is P_0 )

1.	A horizontal tube of length l closed at both ends contains an ideal gas of molecular weight M. The tube is rotated at a constant angular velocity m about a vertical axis passing through an end, Assuming the temperature to be uniform and constant, pressure P at the free end is___ (pressure at fixed end is P_0 )
Answer» `P = P_(0) e^( M omega^(2) t^(2))/( 2 RT)` `P = (P_0)/( 2) e^( M omega^(2) t^(2) )/( 3RT) ` `P= 2P_(0) e^( M omega^(2) t^(2) )/( 4RT)` `P= 3P_(0) e^( M omega^(2) t^(2) )/( RT)` Answer :A
