The length of an elastic wire is x under a tension of 5 N. Its length is y when the tension is 7 N. If the tension becomes 9 N then the length of the wire will be

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 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 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 a metallic wire is L_1 : when tension on the wie is T_1 , and length is L_2 , when the tension in the wire is T_2 , Find original length of the wire.

Length of an elastic string is x then tension 5N is applied and its length will be y when tension 7 N. What will be its original length ?

Length of an elastic string is x then tension 5N is applied and its length will be y when tension 7 N. What will be its original length ?

The length of a metallic wire is l_1 metre when the tension is 4 N and l_2 metre when the tension is 6N respectively. Find the length when the tension is 9N and the actual length of the wire.
