1.	Find the weight of the atmosphere around the earth (take the radius of earth as 6400km.)
Answer» 1600 km 1400 km 2000 km 2600 km Solution :`implies g= (GMe)/(R^2) and phi = -(Gme)/r` `:.phi/g = -r ` `= - (5.4 xx10^7)/(6.0) =-r` `:. 9 xx 10^(7) =r` `:. 9 xx 10^(7) = Re +h` `:. H = 9000 xx 10^3 - Re` `:.h = 9000 km - 6400 km ` `= 2600 km `
