A long cylindrical pipe of radius 20 cm is closed at its upper end and has an airtight piston of negligible mass as shown. When a 50 Kg mass is attached to the other end of the pistion, it moves down by a distance`Deltal` before coming to equilibrium. Assuming air to be an ideal gas, `Deltal//L` (see figure) is close to (g = 10 `ms^(2)` , atmospheric pressure is `10^(5)`  Pascal), img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/KVPY_CP_XI_P1_2017_PHY_E01_014_Q01.png" width="80%"
