Elasticity
my solution has taken the normal formula of U/v = 1/2 x stress x straint to cancel out the equal lengths with which i get the answer 2:1 but the solution they gave, they converted strain = stress/Y and cancelled out Y both sides which makes no sense cause the question says their length is equal and not their Y. Am i wrong or is the solution/answer by nta just incorrect?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.In your method , how you know that delta l in both of the cases is same such that you cancelled it ? @lava
well i
hmmmmmm
idk
Youngs modulus might be same coz it depends on material and both are steel wires
so it's better to convert it terms of stress rather than strain
Does it make sense? @lava
accha
never thought of it that way
thats true
