In a sonometer wire, the tension is maintained by suspending a `50 kg` mass from the free end of the wire. The suspended mass is completely submerged in water, the fundamental frequency will become …………… `Hz`.

Answer

B, D

Explanation

`(v_(1))/(v_(2)) = ((1)/(2l)sqrt(50.7 xx 8)/(m))/((1)/(2l)sqrt(50.7 xx 8)/(m)) rArr v_(2) = v_(1) sqrt((43.2)/(50.7)) = 260 sqrt((43.2)/(50.7)) = 240Hz`.
