Physics · MOTION IN A PLANE
हिन्दीAn insect trapped in a circular groove of radius \( 12\text{ cm} \) moves along the groove steadily and completes \( 7 \) revolutions in \( 100\text{ s} \). What is the angular speed \( \omega \) of the insect? (Take \( \pi = 22/7 \))
Correct answer · Option 3
0.44 rad/s
Explanation
Frequency \( \nu = \frac{7}{100}\text{ Hz} \). Angular speed \( \omega = 2\pi\nu = 2 \times \frac{22}{7} \times \frac{7}{100} = 0.44\text{ rad/s} \).
