Expert Answer:

The masses and pulley system is shown below.
 
 
For mass m1, the forces are given as
 
T - m1g = m1a                                                 ...... (1)
 
Similarly, for mass m2, the forces are given as
 
m2g - T = m2a                                                 ...... (2)
 
From equation (1), we have
 
T = m1g + m1a                                                 ...... (3)
 
Substituting equation (3) in (2) we get
