A satellite revolving in a circular equatorial orbit of radius `R = 2xx10^(4)` km from west to east appears over a certain point at the equator every `t = 11.6` hours. Calculate the mass of the earth. The gravitational contant `G= 6.67 xx 10^(-11) SI` units.   [Hint : `omega_(app) =omega_("earth") or omega_("real") = 2pi ((1)/(T)+(1)/(t))`]
