Question

A mobile is made of identical objects of mass m suspended so that the lowest row has one object, the row above two objects, and the row above three objects. All the strings are at 45° angles. What is the tension in the strings connecting the highest row to the ceiling?

1/2 mg

√2/2 mg

mg

√2/3 mg

3√2/2 mg

Answer 1

Need a picture, as i can't see how the strings can be at 45 degree angles (and 45 degree angle to what?) unless there are several strings per row.
