1.	A sonometer wire resonates with a given tuning fork forming standing waves with five antitodes between the two bridges when a mass of `9kg` is suspended from the wire. when this same tuning fork forming three antitodes for the same positions of the bridges. the value of `M` isA. (a) `25kg`B. (b) `5kg`C. ( c ) `12.5kg`D. (d) `1//25kg`
Answer» Correct Answer - A (a) `f_(0) = (5)/(2l)sqrt((9g)/(mu)) = (3)/(2l)sqrt((Mg)/(mu))` rArr `M = 25 kg`
