\omega_{\mathrm{E}}

and

\omega_{\mathrm{H}}

are the angular velocities of the earth rotating about its own axis and the hour hand of the clock respectively, then

View answer and explanation

Correct option: D

\omega_{\mathrm{E}}=1 / 2 \omega_{\mathrm{H}}

Option D (

\omega_{\mathrm{E}}=1 / 2 \omega_{\mathrm{H}}

) is correct because the Earth's rotation period is 24 hours, while the hour hand's rotation period is 12 hours.
