Answer:

[tex]F=3.11\times 10^{-8}\ N[/tex]

Explanation:

Given that,

Mass of a boy is 70 kg

Mass of a girl is 60 kg

We need to find the force of gravitational attraction between them if they are 3 m away.

The formula for the gravitational force is given by :

[tex]F=\dfrac{Gm_1m_2}{r^2}\\\\F=\dfrac{6.67\times 10^{-11}\times 70\times 60}{(3)^2}\\\\=3.11\times 10^{-8}\ N[/tex]

So, the force between them is [tex]3.11\times 10^{-8}\ N[/tex].

The gravitational attraction force between a 70 kg boy and a 60 kg girl who are 3 m apart is 3 × 10⁻⁸ N.

A 70 kilograms boy and a 60 kilograms girl are 3 meters apart. We can calculate the gravitational force between them using Newton's law of universal gravitation.

[tex]F = \frac{G \times m_1 \times m_2 }{r^{2} } = \frac{\frac{6.67 \times 10^{-11}N.m^{2} }{kg^{2} } \times 70kg \times 60 kg }{(3m)^{2} } = 3 \times 10^{-8} N[/tex]

 

where,

  • F = force
  • G = gravitational constant
  • m₁ = mass of object 1
  • m₂ = mass of object 2
  • r = distance between centers of the masses

The gravitational attraction force between a 70 kg boy and a 60 kg girl who are 3 m apart is 3 × 10⁻⁸ N.
