Question
A spring balance has a scale that can read from 0 to 50 kg. The length of scale is 20 cm. A body suspended from this balance when displaced and released oscillate harmonically with a time period of 0.6 sec. The mass of body is :[g = 10 m/sec2][k=2500N/m]
Options
A.10 kg
B.25 kg
C.18 kg
D.22.8 kg
Solution
F = Kx
500 = K ×
⇒ K = 2500 N/m
T = 2π
⇒ . 6 = 2π
m = 22.8 kg
500 = K ×
⇒ K = 2500 N/mT = 2π
⇒ . 6 = 2πm = 22.8 kg
