Question

If two twins (54 kg each) were 0.02 m apart, what is the force of gravity between them?

Answer 1

Answer:

Force, $F=4.86\times 10^{-4}\ N$

Explanation:

We have,

Masses of two twins are 54 kg each

They are placed at a distance of 0.02 m

It is required to find the force of gravity between them. The formula used to find the gravitational force between masses is given by :

$F=G\dfrac{m_1m_2}{r^2}$

plugging all the known values:

$F=6.67\times 10^{-11}\times \dfrac{54^2}{(0.02)^2}\\\\F=4.86\times 10^{-4}\ N$

So, the force of gravity between them is $4.86\times 10^{-4}\ N$.
