Question

System is shown in figure. Assume there is no friction
Find the acceleration of the blocks and tension in the string.
Take g=10m/s^2​

Answer 1

Answer:

80%

Explanation:

As the string is inextensible and the pulley is smooth the 3 kg block and the 20 kg trolley , both have same magnitude of motion to free body Applying Newton ' s second law of motion to free body diagram of W = 20 kg <br>

<br> Now ,

<br>

<br>

<br> Again applying Newton ' s second law of motion to free body diagram of W = 3 kg we get <br>

<br> Adding (ii) and (iii) , we get <br>

<br>

<br> From (ii) ,
