how to find ( wm) the measurements of the mass m, determined by the accuracy of the scale ∆m.?

Question

its something about Harmonic Oscillations. I have find the wt and the ∆wt. but i need to find wm and ∆wm so plzz help me to find out , which formula do i have to use to find.

the question is about m= mass and w= omega .
i have found omega time(wt) like:
wt=squr root of g*x. but i dont know how to find omega mass(wm) .

Answer 1

Question is not clear. Please clarify the question. What kind of shm is this? spring and mass. simple pendulum what?
Weight = m g change in w = g times change in mass. delta m = delta w /g!
