Answer:
2.67 × 10⁻⁸ N
Step-by-step explanation:
In order to find the gravitational force between two objects whose masses are known, we have to use the following formula:
,
where:
• F ⇒ force
• G ⇒ universal gravitational constant = 6.67 × 10⁻¹¹ m³ kg⁻¹ s⁻²
• m₁, m₂ ⇒ masses of the two objects = 1000 kg
• r ⇒ distance between the objects
Therefore, if we use the formula and information from above, we get:
F =

= 2.67 × 10⁻⁸ N
