A spring balance has a scale that reads from 0 to 5 kg. The length of scale is 20 cm.a body suspended from this spring, when displaced and released ,oscillates with period of 0.60s.what is the weight of body.

Answer 1

Period = 2PI(sqrt(mass/k)
Now for k, full scale is 5kg, of length 20cm, k=5*9.8/.2 N/kg

solve for mass.
Now the Weight of the mass is mass*9.8 ON Earth.
