Two masses of 10kg and 5kg are suspended from a fixed 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. If the downward force continues to act, what is the acceleration of the system?

Question

Two masses of 10kg and 5kg are suspended from a fixed 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. If the downward force continues to act, what is the acceleration of the system? <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/p-19c0b755ikesbuph.jpg" /> (A) 20ms- 2 (B) 10ms- 2 (C) 5ms- 2 (D) Zero

<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/p-19c0b755ikesydzv.jpg" /> asys=(300/15)=20ms- 2

$20 m s^{- 2}$

$10 m s^{- 2}$

$5 m s^{- 2}$

Zero

$a_{sys} = \frac{300}{15} = 20 m s^{- 2}$

20ms−2

10ms−2

5ms−2

Zero

asys​=15300​=20ms−2

$20 m s^{- 2}$

$10 m s^{- 2}$

$5 m s^{- 2}$

$a_{sys} = \frac{300}{15} = 20 m s^{- 2}$
