The length of an elastic string is Xm when the tension is 8 N, and Y m when the tension is 10 N. The length in metres when the tension is 18 N is

Length of an elastic string is 'a' metre when the tension is 4 Newton and 'b' metre when the tension is 5newton. Length in metre when the tension is 9 Newton is. (A) 4a-5b (B) 5b-4a (c) 9b-9a (D) a+b

The length of a rubber cord is l_(1) m when the tension is 4 N and l_(2) m when the tension is 6 N.The length when the tension is 9 N, is

The length of an elastic string is 5 metre when the longitudinal tension is 4 N and 6 metre when the tension is 5 N. If the length of the string (in metre) is "2X" when the longitudinal tension is 9 N (assume Hooke’s law is valid) then the value of X will be :
