Question

What is the gravitational force between two trucks, each with a masof 2.0x10^4 k

Answer 1

Answer:

$6.67\cdot 10^{-3} N$

Explanation:

The gravitational force between two objects is given by

$F=G\frac{m_1 m_2}{r^2}$

where

G is the gravitational constant

m1, m2 are the two masses

r is the separation between the two masses

In this problem, we have

$m_1 = m_2 = 2.0 \cdot 10^4 kg$ the mass of each truck

r = 2.0 m is their separation

Substituting,

$F=(6.67\cdot 10^{-11}) \frac{(2.0\cdot 10^4 kg)^2}{(2.0 m)^2}=6.67\cdot 10^{-3} N$
