Find the acceleration of the block of mass `M` in the situation shown in figure. All the surfaces are frictionless.

A

`(2g)/(3)`

B

`(3g)/(5)`

C

`(g)/(3)`

D

`(g)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`T - M g sin 30^(@) = Ma`
`2Mg - 2T = 2M ((a)/(2))`
Solving these equations, we get `a = (g)/(3)`
