Method 3 of W Mass of a piston shown in Fig. is m and area of cross-se

1.	Method 3 of W Mass of a piston shown in Fig. is m and area of cross-section is A. Initially spring is in its natural length. Find work done by the gas.
Answer» Correct Answer - A::B In the given condition, work is done by the gas only against spring force `kx`. This force is a variable force. Hence, `W=int_0^x(kx)dx=1/2kx^2`
