Question

What is the gravitational force between a 45 kg person, and the Earth at 5.98 x 1024 kg, with a distance of
6.38 x 106 m?
 Object 1 (m1): 45 kg person
 Object 2 (m2): 5.98 x 1024 kg Earth
 Distance: (r): 6.38 x 106 meters
A. 227 N
B. 398 N
C. 441 N
D. 510 N

Answer 1

Answer:

C. 441 N

Explanation:

Gravitational force between two objects can by calculated by the formula

= G m₁m₂ / r² , m₁ and m₂ are masses at distance r

= ( 6.67 x 10⁻¹¹ x 45 x 5.98 x 10²⁴) / ( 6.38 x 10⁶ )²

= 44.09 x 10

= 440.9 N

= 441 N .
