The wires of same length and Young's modulus are subjected to same tensile force. If `triangleI` is the change in length of wire, and c is the circumference of the wire, find the correct graph. The experiment is performed on the wires of different circumference:

Options

A.
B.
C.
D.

Answer

B

Explanation

`triangell=(Fl)/(Ay)=(Fl)/(((pid^2)/(4))y)=(4Fl)/(pid^2y)`,`trianglelprop((1)/(d^2))`
As circimference `(=pid)` increases, `d^2` increases, `(trianglelamda)` decreases
