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 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

The length of a wire l_(1) when tension is 4 N and l_(2) when the tension is 5 N. Then its original length would be

The length of a metal wire is l_1 when the tensionin it is T_1 and is l_2 when the tension is T_2 . The natural length of the wire is

The length of a metal wire is l_(1) when the tension in it is T_(1) and is l_(2) when the tension is T_(2) . Then natural length of the wire is

The length of a metal wire is 10cm when the tension in it is 20N and 12cm when the tension is 40N . Then natural length of the wire is in cm

The length of a metal wire is l when the tension is F and x l when the tension si y F. Then the natural length of the wire 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 :

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 metal wire is l_(1) when the tension in it is F_(1) and l_(2) when the tension becomes F_(2) . Find the natural length of wire.
