Two thin rectangular sheets \( (0.20 \mathrm{~m} \times 0.40 \mathrm{~m}) \) are identical. In the first sheet the axis of rotation lies along the \( 0.20-\mathrm{m} \) side, and in the second it lies along the \( 0.40-\mathrm{m} \) side. The same torque is applied to each sheet. The first sheet, starting from rest, reaches its final angular velocity in \( 8.0 \mathrm{~s} \). How long does it take for the second sheet, starting from rest, to reach the same angular velocity?
(A) \( 0.86 \mathrm{~s} \)
(B) \( 1.4 \mathrm{~s} \)
(C) \( 2.0 \mathrm{~s} \)
(D) \( 1.1 \mathrm{~s} \)
