Question

The sun has a mass of 1.99 x 10-30 kg. Saturn has a

mass of 5.68 x 10^26 kg. The distance between the sun
and Saturn is 1.43 x 10^12 m. Calculate the gravitational
force between the sun and Saturn.

Answer 1

Answer: The gravitational force between the sun and Saturn is
`3.69* 10^(22)N`

Step-by-step explanation:

`F=(Gm_1m_2)/(r^2)`

where F = gravitational force = ?

G = gravitational constant =
`6.674* 10^(-11) Nm^2kg^(-2)`

`m_1` = mass of sun =
`1.99* 10^(30)kg`

`m_2` = mass of saturn =
`5.68* 10^(26)kg`

r = distance between sun and saturn =
`1.43* 10^(12)m`

`F=(6.674* 10^(-11)Nm^2kg^(-2)* 1.99* 10^(30)kg* 5.68* 10^(26)kg)/((1.43* 10^(12)m)^2)`

`F=3.69* 10^(-90)N`

Thus the gravitational force between the sun and Saturn is
`3.69* 10^(22)N`
