Question

What is the force of gravity between two 1000 kg cars separated by a distance of 20 m on a highway?

Answer 1

1.67 × 10^-7 N

Explanation:

Given:

Mass 1 (m1) = Mass 2 (m2) = 1000 kg

Distance (d) = 20 m

Universal gravitational constant (G) = 6.67 x 10^-11 N*m²/kg²

We can calculate the gravitational force using the following formula:

`\begin{gathered} F=G\cdot(m_1\cdot m_2)/(d^2) \\ \\ \text{ We replacing:} \\ \\ F=6.67\cdot10^(-11)\cdot(1000\cdot1000)/(20^2) \\ \\ F=1.67\cdot10^(-7)\text{ N} \end{gathered}`

The force of gravity is 1.67 × 10^-7 N
