A steel wire of a certain length is used to determine the Young modulus of steel, and the result is found to be $E$. A second experiment is then performed with a wire of the same steel, but with half the length and half the diameter. What value is obtained for the Young modulus in this second experiment?
- A$\frac{1}{2}E$
- B$E$
- C$2E$
- D$4E$
