Question

The force between two asteroids is 500,000 N. What will the force be if the masses of both asteroids are doubled?

Answer 1

New force will be equal to
`200000N`

Step-by-step explanation:

We have given gravitational force between two asteroids is F = 500000 N

Now let mass of both asteroids are
`m_1\ and\ m_2`

And distance between them is R

So force of attraction between them is
`F=(Gm_1m_2)/(R^2)`

Now according to question mass of both the asteroids are doubled

So new force of attraction
`F_(new)=(G2m_12m_2)/(R^2)=4F=4* 50000=200000N`
