MCQ
What is the angular velocity of earth
- ✓$\frac{{2\pi }}{{86400}}rad/\sec $
- B$\frac{{2\pi }}{{3600}}rad/\sec $
- C$\frac{{2\pi }}{{24}}rad/\sec $
- D$\frac{{2\pi }}{{6400}}rad/\sec $
✓
Answer
Correct option: A.
$\frac{{2\pi }}{{86400}}rad/\sec $
a
(a)Angular velocity $ = \frac{{2\pi }}{T} = \frac{{2\pi }}{{24}}rad/hr$$ = \frac{{2\pi }}{{86400}}rad/s$
(a)Angular velocity $ = \frac{{2\pi }}{T} = \frac{{2\pi }}{{24}}rad/hr$$ = \frac{{2\pi }}{{86400}}rad/s$
