A sphere rolls down on an inclied plane ...

A sphere rolls down on an inclied plane of inclination `theta`. What is the acceleration as the sphere reaches bottom ?

A

`(5)/(7)gsintheta`

B

`(3)/(5)gsintheta`

C

`(2)/(7)gsintheta`

D

`(2)/(5)gsintheta`

Text Solution

Verified by Experts

The correct Answer is:
A
`a=(gsintheta)/(1+(K^(2))/(R^(2)))=(gsintheta)/(1+(2)/(5))=(5)/(7)gsintheta`.
