Please help with the following problem. Provide detailed calculations.

A scale is attached to the ceiling and a mass of 1.00 kg hangs from it. It reads 9.81 N. Another identical scale at the right is connected by perfect strings passing over perfect pulleys to two 1.00 kg masses hanging vertically at the end of the strings (the 1 kg masses are on opposite sides).

The scale at right reads
exactly 9.81 N.
more than 9.81 N, but not quite twice as much.
less than 9.81 N.
exactly 19.62 N.

Solution Summary

This solution helps with a question about classical mechanics, equilibrium specifically. When one mass is connected the net force on the scale is equal to the weight of the mass suspended. Let us say that the mass of the body used is m. Please help answer the following problem.
