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

A

zero

B

`2 ms^(-2)`

C

`1.5 ms^(-2)`

D

`5 ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
A
Angle of repose `= tan^(-1) ((1)/(sqrt(3))) = 30^(@)`. Som the block is just at rest. ?
