Three masses of 1 kg, 6 kg and 3 kg are ...

Three masses of 1 kg, 6 kg and 3 kg are connected to each other with threads and are placed on a table as shown in figure. What is the accelration with which the system is moving? Take `g=10ms^(-2)`:

A

Zero

B

`2 ms^(-2)`

C

`4 ms^(-2)`

D

`3 ms^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
B
`3g-T_(2)=3a`
`T_(2)-T_(1)=6a`
`T_(1)-g=a`
`therefore 2g=10a`
`a=2m//s^(2)`
