JEE Main 2022 Physics question
A steel wire of length 3.2 m = ) and a copper wire of length 4.4 m = ), both of radius 1.4 mm are connected end to end. When stretched by a load, the net elongation is found to be 1.4 mm. The load applied, in Newton, will be: (Given = 22/7)
Answer: (4)
Solution
The same load W acts on both wires, so m. With 10^{-3})^{2}$ = 6.16
