Question
For the system shown in the figure, The acceleration of the mass m4immediately after the thread x is cut will be , (Assume that the threads are weightless and inextensible , the spring are weight less, the mass of pulley is negligible and there is no friction )
Options
A.0
B.
C.
D.
Solution
T1 = (m1 + m2) g
T1 - T2 = (m3 + m4) g T2 = (m1 + m2 - m2 - m4) g
Net Force acting immediately after cutting x = T2
Acceleration =
