View Answer & Solution
Correct answer · Option B
\( \frac{1500}{\pi}\text{ N}\cdot\text{m} \)
Explanation
\( \omega = \frac{2\pi \times 300}{60} = 10\pi\text{ rad/s} \). Instantaneous power \( P = \tau \omega \implies \tau = \frac{P}{\omega} = \frac{15000}{10\pi} = \frac{1500}{\pi}\text{ N}\cdot\text{m} \).
