Acceleration of a solid cylinder rolls on inclined plane with a `30^(@)` angle is ……………

Options

A. `(g)/(3)`
B. `(g)/(2)`
C. `g`
D. `(g)/(4)`

Answer

A

Explanation

Acceleration of solid cylinder rolls down from inclined plane,
`a=(2)/(3)gsintheta`
`=(2)/(3)xxgxxsin30^(@)`
`=(2)/(3)xxgxx(1)/(2)`
`therefore a=(g)/(3)`
