Question
Calculate the mass of the sun if the mean radius of the earth′s orbit is 1.5 × 108 km and G = 6.67 × 10-11 N m2 /kg2.
Options
A.M = 2 × 1030 kg
B.M = 3 × 1030 kg
C.M = 2 × 1015 kg
D.M = 3 × 1015 kg
Solution
In case of orbital motion as v = 
so T = 
= 2πr 
, i.e., M = 
M =
[as T = 1 year = 3.15 × 107s] i. e. M = 2 × 1030 kg
so T = = 2πr , i.e., M = M =
[as T = 1 year = 3.15 × 107s] i. e. M = 2 × 1030 kgCreate a free account to view solution
