Question

Calculate the force of gravitation between the earth and the sun,given that the mass of earth = 6× 10^24 kg and of the sun = 2 × 10^30. The average distance between the two is 1.5×10^11.

Answer 1

hi friend
-----------
the gravitational force between the Earth and the Sun is 35.5 7 x 10 ^ 21 Newton.

I had shown the calculations in the image that I have attached.
if it is helpful then please marked it as brainliest..

Answer 2

Given m =  6 * 10^24g

           M =  2 * 10^30
 
           r = 1.5*10^11 m

           G = 6.6*10^-11

We know that F = GMm/r^2

                           = (6.6*10^-11) * (6 * 10^24)(2 * 10^30)/(1.5*10^11)^2

                           = (6.6 * 6 * 2)(10^30 + 24 - 11)/2.25 * 10^22

                           = 79.2 * 10^43/2.25 * 10^22

                          = 79.2 * 10^43 - 21/2.25

                          = 35.2*10^21 N.


Hope this helps!
