Question

Compute the gravitational attraction force between the sun and the earth(the mass of the sun is 2×10³⁰kg, that of the earth is 6×10²⁴kg and their separation is d=1.5×10¹¹m.

​

Answer 1

35.57 x 10²¹ N

Step-by-step explanation:

m(s) = 2 x 10³⁰ kg

m(e) = 6 x 10²⁴ kg

d = 1.5 x 10¹¹

G = 6.67 x 10⁻¹¹

F = Gm1m2/d²

= 6.67 x 10⁻¹¹ x 2 x 10³⁰ x 6 x 10²⁴ / 2.25 x 10²²

= 80.04 x 10⁴³ / 2.25 x 10²²

= 35.57 x 10²¹ N
