Question

tension of body is reduced to half and mass per unit length is doubled what is the speed?​

Answer 1

Answer:

Velocity of waves in string being directly proportional to sqrt of tension and inversely proportional to the sqrt of mass per unit

length .The tension being doubled & mass per unit length being halved makes their effective ratio 4 times the original, so sqrt of same will be 2 times original,=> velocity is doubled.So fundamental frequency being velocity divided by wave length, is to be doubled

this is your answer
