Question
The rotation of the Earth having radius R about its axis speeds upto a value such that a man at latitude angle 60o feels weightless. The duration of the day in such case will be
Options
A.
B.
C.
D.
Solution
g′ = g - ω2r cos 60
g′ = g - ω2R cos2 60
g′ = 0, g = ω2R cos2 60

= ω , t = 
g′ = g - ω2R cos2 60
g′ = 0, g = ω2R cos2 60
