Question

) 7 ) The mass of the earth 6 x 1024 kg . The distance between the earth and the sun is 1.5 x 10 " m . If the gravitational force between the two is 3.5 x 1022N , what is the mass of the sun ? G = 6.7 x 10 Nm kg 2. ( Ans - 1.96 x 100 kg)​

Answer 1

ANSWER

ANSWERGiven that,

Earth of mass M=6×10 ^24 kg

Gravitational force F=3.5×10 ^2 N

Distance between earth and sun r=1.5×10 ^11 m

Mass of the sun = m

of the sun = mNow,

The gravitational force is

gravitational force is F= GMm/r²

3.5×10 ^2

2 =

2 = (1.5×10 ^11 ) 2

11 ) 2 6.67×10 ^−11 ×6×10 ^24 ×m

24 ×m

24 ×m m= 6.67×10 ^−11 ×6×10 ^24

24 3.5×10 ^2 ×1.5×10 ^11 ×1.5×10 ^11

11

11

11 m=0.1967×10 ^11 kg

11 kg m=1.97×10 ^10 kg

10 kgHence, the mass of the sun is 1.97×10 ^10 Kg
