The work done on a wire of volume of 2 ~cm ^3 is 16 10^2 ~J . If the young's modulus of the material of the wire is 4 10¹² Nm ⁻² . Then the strain produced in the wire is
Options
- A0.03 m
- B0.04 m
- C0.01 m
- D0.02 m
Correct answer
D. 0.02 m
Step-by-step solution
aligned & W =16 10^2 ~J , ~V =2 ~cm ^3=2 10⁻⁶ ~m ^2 & Y =4 10¹² Nm ⁻² & ~W = 1 2 y ^2 ~V = 2 ~W Yv & = 2 16 10^2 4 10¹² 2 10⁻⁶ =0.02 aligned
