The tension on point 1 for the three objects moving on a horizontal frictionless surface is 4 N.
Net acceleration of the masses
The acceleration of the masses is determined from the net force acting on the mass.
a = ∑F/∑m
a = (3F - 2F)/ (m + 2m + 3m)
a = F/(6m)
Tension at point 1
T1 = m₂a
T1 = (2m) x a
T1 = (2m) x F/(6m)
T1 = (2F)/6
T1 = (2 x 12)/6
T1 = 4 N
