What is the linear velocity of a body on the surface of the earth at the equator? Given the radius of the earth is $6400 km$ . Period of rotation of the earth = $24 hours$ .

Options:

Answer:

Solution:

$ω = \frac{2 π}{24 \times 60 \times 60} = 7.26 \times 1 0^{- 5} rad s^{- 1}$

$v = r ω = 6400 \times 1 0^{3} \times 7.26 \times 1 0^{- 5} = 465 m s^{- 1}$
