Questions
A sonometer wire with a suspended mass of M =1kg is in resonance with a given tuning fork The apparatus is taken to the moon where the acceleration due to gravity is 1/6 that on the earth. To obtain resonance on the moon, the value of M should be
detailed solution
Correct option is C
On earth, n1=12lMgm=12lgm On moon n2=12lM(g/6)m=12lMg6m For resonance, n1=n2 ∴ 12lgm=12lMg6m or M=6kgTalk to our academic expert!
