Answer:
The answer to your question is: F = 6.69 x 10²⁰ N
Explanation:
To solve this problem we need to use the Newton's law of universal gravitation.
F = G(m1m2)/r²
where
F = ?
G = 6.674×10−11 N · (m/kg)2 is the gravitational constant
m1 = Neptune mass = 1.02 x 10²⁶ kg
m2 = Sun mass = 1.99 x 10³⁰ kg
r orbital distance among the planets = 4.50 x 10¹² m
Substitution
F = 6.674×10−11 N · (m/kg) x 1.02 x 10²⁶ kg x 1.99 x 10³⁰ kg / (4.50 x 10¹² m)²
F = 1.355 x 10⁴⁶ / 2.025 x 10²⁵
F = 6.69 x 10²⁰ N
