A balance and torque experiment is conducted with an UN-balancedruler.
Length of the ruler: 1 m
Mass of the ruler: 149 g
The pivot is at the 32-cm mark.
A 77-g mass is located at the 24-cm mark of the ruler.
We want to balance the ruler by placing another mass at the11-cm mark.
What should be magnitude of this additional mass?
