A body of mass `m =18kg` is placed on an inclined plane the angle of inclination is `alpha =37^(@)` and is attached to the top end of the slope with a thread which is parallel to the slope. Then the plane slope is moved with a horizontal acceleration of a. Friction is negligible.

At what acceleration will the body lose contact with plane .

A

Tension in the thread for `a=(5)/(6) m//sec^(2) "is " 12N`

B

Tension in the thread for `a=(5)/(6) m//sec^(2) ` is 24 N

C

The block loses contact with plane when acceleration becomes`(10)/(3) (m)/(s^(2))`

D

The block loses contact with plane when acceleration becomes`(40)/(3) m//s^(2)`
