Copper of fixed volume V is drawn into a wire of length l. When this wire is subjected to a constant force F, the extension produced in the wire is ∆l. If Y represents the Young’s modulus, then which of the following graphs is a straight line? [NEET 2014 model]
A. ∆l versus V
B. ∆l versus Y
C. ∆l versus F
D. ∆l versus 1l
