Question

5. Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth = 6 x 1024 kg and of the Sun = 2 x 1030 kg. The average distance between the two is 1.5 x 1011 m.​

Answer 1

Answer:

Step-by-step explanation:

Given :       Mass of earth    m=6×10  

24

kg

                  Mass of Sun    M=2×10  

30

kg

                 Distance between sun and earth       r=1.5×10  

11

 m

Force of gravitation between them       F=

Answer 2

Answer:

3.557×1022N

Step-by-step explanation:

Given :       Mass of earth    m=6×1024kg

                   Mass of Sun    M=2×1030kg

                  Distance between sun and earth       r=1.5×1011 m

Force of gravitation between them       F=r2GMm

F=(1.5×1011)26.67×10−11×(6×1024)×(2×1030)=3.557×1022  N

hope use full pls thanks me
