Force & Motion: Find Force Values for 600g Object

[alexas]

Homework Statement

What force values go in the blanks on the horizontal scale?
The figure (attached as an image) shows an acceleration-versus-force graph for a 600 g object.

Homework Equations

F=MA

The Attempt at a Solution

I was thinking from F=ma that:
a) F=5X600 = 3000N
b) F=10X600 = 6000N

But my answer is definitely not being accepted by the computer so i must be doing something wrong. Any ideas?

I got it... =)

After much trial and error i realized it. Its in Grams should i should have been multiplying by 0.6 NOT 600

I'm sure i'll be back here soon though. Thanks!
