Question: What is the angular velocity of earth[IIT JEE 2005]
Options:
A) $ \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 $
Show Answer
Answer:
Correct Answer: A
Solution:
Angular velocity $ =\frac{2\pi }{T}=\frac{2\pi }{24}rad/hr $
$ =\frac{2\pi }{86400}rad/s $
