A circular solid shaft of span $L=5 \mathrm{~m}$ is fixed at one end and free at the other end. A torque $T=100 \mathrm{~kN}$.m is applied at the free end. The shear modulus and polar moment of inertia of the section are denoted as $G$ and $J$, respectively. The torsional rigidity $G J$ is $50,000 ~\mathrm{kN} \cdot \mathrm{m}^2 / \mathrm{rad}$. The following are reported for this shaft:

$\text{Statement i)}$ The rotation at the free end is $0.01~ \mathrm{rad}$
$\text{Statement ii)}$ The torsional strain energy is $1.0~ \mathrm{kN}$.m

With reference to the above statements, which of the following is true?

  1. Both the statements are correct
  2. $\text{Statement i)}$ is correct, but $\text{Statement ii)}$ is wrong
  3. $\text{Statement i)}$ is wrong, but $\text{Statement ii)}$ is correct
  4. Both the statements are wrong
