In the figure given below, with what acceleration does the block of mass m will move? (Pulley and strings are massless and frictionless)

A

`(g)/(3)`

B

`(2g)/(5)`

C

`(2g)/(3)`

D

`(g)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
C

( c) Acceleration `a =[(m_(2)-m_(1))/(m_(2)+m_(1))]g`
`=[(5m-m)/(5m+m)]g=(4m)/(6m)g=(2)/(3)g`
