Question
A mass of 125gm is suspended from a light spring, thefrequencey of its simple harmonic vibration is 2.6Hz, if the massis reduced to 50gms and is suspended from the same spring. Find thefrequence? [4.12Hz] A mass of 125gm is suspended from a light spring, thefrequencey of its simple harmonic vibration is 2.6Hz, if the massis reduced to 50gms and is suspended from the same spring. Find thefrequence? [4.12Hz]Explanation / Answer
Frequency of harmonic motion, f = (1/2)(k/m) Thus, f is inversely proportional to m Hence, f2/f1 =(m1/m2) f2 = f1*(m1/m2)= 2.6*(125/50) = 4.11 Hz
