Three blocks of mass m1,m2,m3 are connected linearly by a massless string on a frictionless table.They are..?

pulled by a force t3=40 N. if m1=10kg m2=6kg, m3=4kg .Find the tension t2?

total mass of system = 20 kg
acceleration of system = F/m = 40 N/20 kg = 2.0 m/s2

t3
<------3---<----2-----1

string t2 pulls blocks 2 and 1, so
the tension in the string t2 = (m1 +m2) a = 32 N
