In the system shown in fig., all pulleys are mass less and the string is inextensible and light.
(a) After the system is released, find the acceleration of mass `m_(1)`
(b) If `m_(1) = 1 kg, m_(2) = 2 kg "and" m_(3) = 3 `kg then what must be value of mass `m_(4)` so that it accelerates downwards?

Text Solution

Verified by Experts

The correct Answer is:
`a_(1) = g(1 - (4M)/(m_(1)))`
(b) `m_(4) gt (18)/(11) "kg"`
