A horizontal inspection panel can turn about a pivot at its geometric centre. The panel's centre of mass is at the pivot, so its weight acts through the pivot. A downward force of 8 N acts 0.15 m to the left of the pivot. A downward force of 3 N acts on the right.
At which distance from the pivot must the 3 N force act to keep the panel balanced?
0.40 m from the pivot
0.056 m from the pivot
0.15 m from the pivot
1.2 m from the pivot
