Question

A 65 kg astronaut in the international space station is approximately 3.81 × 10^8 m away from the moon. How much gravitation force does she feel? The mass of the Moon is 7.355 × 10^22 kg.

Answer 1

`F = 2.2 * 10^(-3) N`

Step-by-step explanation:

Force of gravitation between Astronaut and Moon is given by the Universal law of gravitation

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

now we will have

`m_1 = 7.355 * 10^(22) kg`

`m_2 = 65 kg`

`r = 3.81 * 10^8 m`

now from above formula we have

`F = ((6.67 * 10^(-11))(65)(7.355 * 10^(22)))/((3.81 * 10^8)^2)`

`F = 2.2 * 10^(-3) N`
