Question

Which of the following is not the law of a stretched string ? ( n , l , T and m are frequency of vibration , length of vibrating string , tension in string and linear mass density , respectively .)

Answer 1

Answer: law of frequency of vibration.

Explanation: only three laws is there for stretched string (1)law of length:- f is inversely proportional to l

(2) law of tension:- f is directly proportional to square root of T

(3) law of linear density f is inversely proportional to square root of linear density
