## Homework Statement

Two masses, measuring 800g and 400g respectively, are attached to spring scales and an Atwood Machine. What will the reading of each scale be?

View attachment 52223

## Homework Equations

Fg = mg

## The Attempt at a Solution

I think that the reading on each spring scale will equal the force of gravity acting on each attached mass.

For Scale 1:

Reading = Fg = mg

= (0.8kg)(9.8N/kg) = 7.84 N

For Scale 2:

Reading = Fg = mg

= (0.4kg)(9.8N/kg) = 3.92 N

Is this correct?
