The fixed non-conducting cylinder shown in figure has a noconducting heavy piston of mass `M` that can slide without friction. The area of piston is `S` and the cylinder is filled with an ideal gas `(lambda=1.5)` with an initial volume `V` and an initial pressure `P`. Assume that the outside pressure on the piston is zero (vaccum). (Neglect acceleration due to gravity).

The initial acceleration of piston is:

Options

A. `(PA)/(lambdaM)`
B. `(lambdaPA)/(M)`
C. `(PA)/(M)`
D. `(PA)/(lambda-1)`

Explanation

The initial force on the piston is `PA`
`because a=(PA)/(M)`
