A piston of mass m can move without friction in a uniform cylinder closed at one end. A gas is enclosed in it. Then:

Answer:

B, C

Solution:

With the closed end at the bottom, $P = P_{0} + \frac{m g}{A}$ .

With the closed end at the top, $P = P_{0} - \frac{m g}{A}$ , which is

less. Equality is possible for a suitable tilt where the piston weight

is balanced by other effects. A is false because it says "will be" and D

is false because lower pressure is possible. B and C.
