What is the acceleration of the upper block of the system as shown in the figure? Assume pullies and strings area ideal. Given `m_(A)~~0`

`4g`

`2g`

`g`

`g/2`

Text Solution

Verified by Experts

The correct Answer is:

From F.B.D. We get `mA-4T=mA_(2)`
`mA+2t-T=mA_(1)`

On solving these two get
`a_(A)=4g`
