If acceleration of M is a then acceleration of m is

A

`3a`

B

`a/3`

C

a

D

`sqrt(10)a`

Text Solution

Verified by Experts

The correct Answer is:
D
Net tension on M
`equiv sqrt((3T)^(2)+T^(2))=sqrt(10)T`

Now from acceleration`xx` Tension = constant
`rArr a_(M)(sqrt(10)T)=a_(m)(T)rArr a_(m)(sqrt(10))a_(M)=sqrt(10)a`
OR
Net acceleration of m
`equiv sqrt(a^(2)+(3a)^(2))=sqrt(10)a`
