1.	The following four wires are made of the same material. Which of these will have the largest extension when the same tension is applied?
Answer» LENGTH = 200 cm, diameter = 0.5 mm length = 200 cm, diameter = 1 mmm length = 200 cm, diameter = 2 mm length = 200 cm, diameter = 3 m Solution :`Y=(Fl)/(Ax)` `Y=(Fl)/(((PID^(2))/(4))x)` Y is same. `thereforex=(Fl)/(((pid^(2))/(4))y)` `thereforexprop(1)/(d^2)` Hence the value of l must be most and that of d must be least.
