Question

Two identical balls of masses of 1000 kg each have distance of 50m between their centers. Find the gravitational force between two balls

Answer 1

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:

`\boxed{F = G(\ m_1m_2)/(r^2)}`,

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 =
`6.67 * 10^(-11) * (1000 * 1000)/((50)^2)`

= 2.67 × 10⁻⁸ N
