Question

calculate the average distance of earth from the sun if sun exerted on gravitational force of 3.55×10^22N on earth. mass of sun is 2×10^30kg​

Answer 1

Answer:

147.94 Million km is your answer

Answer 2

The average distance between earth and sun is ≅ $1.501 \times 10^{11}$ m

Explanation:

Given :

Mass of sun $M_{s} = 2 \times 10^{30}$ Kg

Mass of earth $M_{e } = 6 \times 10^{24 }$ Kg

Gravitational force $F = 3.55 \times 10^{22}$ N

From the law's of gravitation,

⇒  $F = \frac{GM_{e } M_{s} }{r^{2} }$

Where $G =$ gravitation constant and it's value is $6.67 \times 10^{-11}$, $r =$ average distance between earth and sun.

    $r^{2} = \frac{6.67 \times 10^{-11} \times 6 \times 10^{24} \times 2 \times 10^{30} }{3.55 \times 10^{22} }$

      $r = \sqrt{225.46 \times 10^{20} }$

      $r = 1.501 \times 10^{11}$ m
