Physics · MOTION IN A PLANE
हिन्दीFor an insect moving in a circular groove of radius \( 12\text{ cm} \) with a constant angular speed of \( 0.44\text{ rad/s} \), what is the magnitude of its centripetal acceleration \( a_c \)?
Correct answer · Option 4
\( 2.3\text{ cm/s}^2 \)
Explanation
Centripetal acceleration \( a_c = \omega^2 R = (0.44\text{ rad/s})^2 \times 12\text{ cm} = 0.1936 \times 12 \approx 2.3\text{ cm/s}^2 \).
