3-2.Motion in Plane
easy
પોતાની ધરીની આસપાસ પૃથ્વીની કોણીય ઝડપ ............. $rad / s$ છે ?
A$\frac{\pi}{43200}$
B$\frac{\pi}{3600}$
C$\frac{\pi}{86400}$
D$\frac{\pi}{1800}$
Solution
(a)
Angular speed $=\frac{2 \pi}{T}$
$T \rightarrow$ Time period of earth $=24 h$
$\omega=\frac{2 \pi}{24 \times 60 \times 60}=\frac{\pi}{43200} \,rad s ^{-1}$
