JEE Main 5 April 2026, Shift 2, Physics Q46

Question 46 of 75 in this shift, Physics question 21 of 25, Section B.

A copper wire of length 3 m is stretched by 3 mm by applying an external force. The volume of the wire is

600\times10^{-6}\ \mathrm{m^3}

. The elastic potential energy stored in the wire in stretched condition would be __________ J. (Given Young modulus of copper =

1.1\times10^{11}\ \mathrm{N/m^2}

)
