To find the tensions in strings 1 and 2, we need to use the equations for Newton's Second Law in the vertical direction for each block:

For the 4.00 kg block:
T1 - mg = (4.00 kg)(2.20 m/s^2) --> T1 = 54.4 N

For the 2.00 kg block:
T2 - mg = (2.00 kg)(2.20 m/s^2) --> T2 = 24.0 N

Therefore, the magnitudes of T1 and T2 are 54.4 N and 24.0 N, respectively. The answer is E.
