We can use the fact that the vertical force on the lamp must be zero (since it is not accelerating in the vertical direction). The tension in the horizontal wire is therefore equal in magnitude to the tension in the vertical wire, which is given as 417 N. So the answer is (B).

A Lamp with a Mass M = 42
