From the information given, the magnitude of the force on each chain will be 314.58 N.
From the complete information, we have a vertical force of 100 lb mass downward.
Mass = 100 lb = 45.35 kg
Weight = 45.35 x 9.81 = 444.88 N
When the force is resolved, we will have 2Fcos45 in an upward direction. This will be:
2Fcos45 = 444.88 N
F = 314.58 N
Therefore, the magnitude of the force on each chain is 314.58N.
