In the experiment, the curve between `DeltaX` and `DeltaW` is shown as dotted line `(l)`. If we use an another wire of same material, but with double length and double radius. Which of the curve is expected.

Text Solution

Verified by Experts

Initially slope `= (Deltax)/(Deltaw) = (l_(0))/((pir^(2))(Y))`
in second case (slope) `=(2l_(0))/(pi(2r)^(2)Y)=(1)/(2)(l_(0))/((pir^(2))Y)`
so slope will be halved .
