The coefficient of friction for an inclined plane and a biock is `(1)/sqrt(3)`what is the acceleration of the block when angle of inclination of the plane is `30^(@)` ?

Options

A. `sqrt(3)ms^(-2)`
B. `(1)/(sqrt(3))ms^(-2)`
C. Zero
D. `3ms^(-2)`

Answer

c

Explanation

So the correct choice is (a). 57. `a = g sin theta - mug cos theta = g xx sin 30^(@) -(1)/(sqrt3)` g.`cos 30^(@)`
`=(g)/(2)-(g)/(2)=zero`
(c) is the choice
