Two masses of 10kg and 5kg are suspended...

Two masses of `10kg` and `5kg` are suspended from a rigid support as shown in figure. The system is pulled down with a force of `150N` attached to the lower mass. The string attached to the support breaks and the system accelerates downwards

In case the force continues to act. what is the acceleration of the system ? .

A

`20 m//s^(2)`

B

`10m//s^(2)`

C

`5m//s^(2)`

D

zero

Text Solution

Verified by Experts

The correct Answer is:
A
`(150+150)/(15)=20 m//s^(2)`
