A) 1 : 1
B) 1 : 2
C) 2 : 1
D) 4 : 1
Correct Answer: C
Solution :
Young modulus \[Y=\frac{W.I}{A\Delta I}\] \[l,A\]and\[\Delta l\]are the same for both the wires. \[Y\propto W\] \[\frac{{{Y}_{s}}}{{{Y}_{b}}}=\frac{{{W}_{s}}}{{{W}_{b}}}=\frac{2}{1}\] \[{{W}_{s}}:{{W}_{b}}=2:1\]You need to login to perform this action.
