Question

A cylindrical tube of uniform cross-sectional area $A$ is filled with two air tight frictionless pistons. The pistons are connected to each other by a metallic wire. Initially, the pressure of the gas is $p_o$ and temperature is $T_o$, atmospheric pressure is also $p_o$. Now, the temperature of the gas is increased to $2T_o$, the tension of wire will be

• A. $2p_oA$
• B. $p_oA$
• C. $\frac {p_oA}{2}$
• D. $4p_oA$

Answer 1

Answer: (B)

$p_oA$

Answer 2

The correct option is (B): $p_oA$.
