A round uniform body of radius `R`, mass `M` and moment of inertia 'I' rolls down (without slipping) and inclined plane making an angle `theta` with the horizontal. Then its acceleration is.

Options

A. `(gsintheta)/(1+(I)/(MR^(2)))`
B. `(gsintheta)/(1+(MR^(2))/(I))`
C. `(gsintheta)/(1-(I)/(MR^(2)))`
D. `(gsintheta)/(1-(MR^(2))/(I))`

Explanation

`a=(gsin theta)/(1+k^(2)//R^(2)) =(g sin theta)/(1+(mk^(2))/(mR^(2)))=(g sin theta)/(1+(I)/(mR^(2)))`
