Gravitation

Question: The angular velocity of the earth with which it has to rotate so that acceleration due to gravity on 60o latitude becomes zero is (Radius of earth = 6400 km. At the poles $g = 10\,m{s^{ - 2}})$

1) $2.5 \times {10^{ - 3}}rad/s$

2) $5.0 \times {10^{ - 1}}rad/s$

3) $10 \times {10^1}rad/s$

4) $7.8 \times {10^{ - 2}}rad/s$
