An ice cube is kept on an inclined plane...

An ice cube is kept on an inclined plane of angle `30^(@)`. The coefficient to kinetic friction between the block and incline plane is `1//sqrt(3)`. What is the acceleration of the block ?

A

Zero

B

2 `m//s^(2)`

C

`1.5 m//s^(2)`

D

`5 m//s^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
a = `g (sin theta - mu cos theta) = g [ (1)/(2) = (1)/(sqrt3) xx (sqrt3)/(2)] = 0`
