Answer:
2.0 × 10^ 30 kg
Explanation:
here constants used will be mass of earth which is 6 × 10 ^ 24 kg
distance between earth and sun is 1.50 × 10 ^ 11 m
G = 6.67 × 10 ^ -13 N m^2 / kg^2
formula is F = G m1 m2 / r^2 where F is gravitational force , G is universal gravitational constant , m1 is mass of Sun , m2 is mass of earth , r is distance between earth and sun
making m1 as subject matter we get
m1 = (F r^2)/(G m2)
m1 = {3.52 × 10 ^22 N × (1.50 × 10 ^ 11 m)^2 } / ( 6.67 × 10 ^ -13 N m^2 / kg ^2 × 6 × 10 ^24 kg )
m1 = ( 3.52 × 10 ^22 × 2.25 × 10 ^22 ) / ( 4.002× 10 ^14 ) kg
m1 = 1.979 × 10 ^ 30 kg
m1 = 2.0 × 10 ^ 30 kg
