mass is at
mark
mass is at
mark
Scale is Pivoted at
For scale to be in equilibrium net torque must be equal to zero
Taking ACW as positive thus
Therefore a net torque of 0.04 g is required in CW sense which a mass can provide at a distance of
from pivot
therefore in meter stick it is at a distance of
