Question

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

Answer 1

Force,
`F=4.86* 10^(-4)\ N`

Step-by-step 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(m_1m_2)/(r^2)`

plugging all the known values:

`F=6.67* 10^(-11)* (54^2)/((0.02)^2)\\\\F=4.86* 10^(-4)\ N`

So, the force of gravity between them is
`4.86* 10^(-4)\ N`.
