Calculate the apparent weight if a body of 10 kg of place of latitude `60^(@)`. The radius of the earth `= 6.4 xx 10^(6)` m
[Hint : Apparent weight `= mg - mv^(2) cos ^(2) lamda/r` where `lamda` is the latitude of the place
`= mg - m omega^(2) r cos^(2) lamdaN`
`= (m - m omega^(2)r cos^(2) lamda//g)kg`]

Answer

9.9914 kg
