A cylindrical adiabatic container of total volume 2Vo is divided into two equal parts by a conducting piston which is free to move as shown in the figure. Each part contains identical gas at pressure P 0 . Initially the temperatures of the left and right parts are 4To and to respectively. An external force is applied on the piston of area A to keep the piston at rest. The value of external force required when thermal equilibrium is reached is
