Paragraph: P_ 14-16 : Paragraph for Questions Nos. 14 to 16 A fixed thermally conducting cylinder has a radius R and height L₀ . The cylinder is open at its bottom and has a small hole at its top. A piston of mass M is held at a distance L from the top surface as shown in the figure. The atmospheric pressure is p₀ . Question: The piston is now pulled out slowly and held at a distance 2 L from the top. The pressure in
Options
- Ap₀
- Bp₀ 2
- Cp₀ 2 + M g R^2
- Dp₀ 2 - M g R^2
Correct answer
A. p₀
Step-by-step solution
Since it is open from top, pressure will be p₀ . Option (a) is correct.
