This may be a simple standard qn but im not gettin the final ans.
An ideal gas is contained in a piston cylinder arrangement. Area of piston is A and its mass is M.
The surrounding atm pressure is P0. Under equilbrium condition, volume of the gas is V0 . Find the angular frequency of small vertical oscillations of the piston assuming expansion and compression of the gas to be adiabatic. assume adiabatic constant =.
The ans is
