Question

A 61.5 KG student sits at a desk 1.2 5M away from a 70.0 KG student. What is the magnitude of the gravitational force between the two students?

Answer 1

mass of two students are

`m_1 = 61.5 kg`

`m_2 = 70 kg`

distance between them is given as

`r = 1.25 m`

now gravitational force between them is given as

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

now plug in all values

`F = (6.67* 10^(-11) * 61.5 * 70)/(1.25^2)`

`F = 1.84 * 10^(-7) N`

so above is the force of gravitation between them
