## Homework Statement

The strings attach to a scale which reads the force. What is the force that the scale will read?

## Homework Equations

F=ma according to Newton's Laws.

## The Attempt at a Solution

Thinking logically, I simply calculated the force of the left side:

F=ma => (2kg)(9.8m/ssq) = 19.6N

Then calculated the force of the right side:

F=ma => (1kg)(9.8m/ssq) = 9.8N

Then simply subtracted the two, leaving the final answer to be 9.8N. My teacher told me that this is not the right answer. I'm confused as to how else I could have done this problem. Thanks for the help!
