D) 62 N 
E) 57 N

Quizplus · Accepted Answer

Assuming the system is in equilibrium: 
Tension in string 1 + Tension in string 2 = Weight of M
Tension in string 2 = M * g = 1.1 kg * 9.8 m/s^2 = 10.78 N

Therefore, tension in string 1 = Weight of M - Tension in string 2 =  M * g - 10.78 N = 1.1 kg * 9.8 m/s^2 - 10.78 N = 39.62 N ≈ 40 N.
