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) Angular velocity $=\frac{2 \pi}{T}=\frac{2 \pi}{24} rad / hr =\frac{2 \pi}{86400} rad / s$
