\omega _2 ^2 = \omega _1 ^2 + 2 \alpha \theta \\\\ 0 = ( 2 \pi*\frac{3}{60} ) ^2 - 2 \times 2 \pi \times 2 \pi \alpha \\\\ \alpha = \frac{1}{800} \\\\ T = I\alpha = \frac{mr ^2}{2} d \\\\ = 2 \times 10 ^{-6}


Option 1)

2 \times 10 ^{-6} Nm

Option 2)

2 \times 10 ^{-3} Nm

Option 3)

12 \times 10 ^{-4} Nm

Option 4)

2 \times 10 ^{6} Nm
