Find the net force on a,b and c. Given ma=363kg mb=517kg and mc=154kg.
a<0.5m>b<0.25>c
This was a question given to our class by our physics teacher ... he did not show us how to do it. So any help/steps involved to solve this problem would be much appreciated.

For each of the three masses, they want to to add the gravitational attraction forces due to the other two. For mass b, the attraction forces will be in opposite directions.
Use Newton's Universal Law of Gravity, with the factor G
