Let us assume that whole system is moving with acceleration a
For m mass block,
A force F is acting in forward direction and T1 is acting in backward direction, then
F - T1 = ma .........(i)
For 3m mass block,
A force T1 is acting in forward direction and T2 is acting in backward direction, then
T1 - T2 = 3ma .........(ii)
For 5m mass block,
A force T2 is acting in forward direction, then
T2 = 5ma .........(iii)
On adding equation (i) & (ii) we get
T1 = 8ma
16 = 8ma
ma = 2........(iv)
Put this value of ma in equation (iii)
T2 = 5 ma
T2 = 5*2 = 10 N
See the answer was simple but on one condition that you should have firm grip on your concepts!
