Two masses `M_(1) " and " M_(2)` are attached to the ends of a string which passes over a pulley attached to the top of an inclined plane. The angle of inclination of the plane is `30^(@)` and `M_(1)=10 kg, M_(2)=5kg`. What is the acceleration of mass `M_(2)` ?

A

`10 ms^(-2)`

B

`5 ms^(-2)`

C

zero

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
C
( c) Since `M_(1)g sin 30^(@)=M_(2)g`
`therefore` Net pulling force=0
or acceleration of system =0
