An astronaut weighs 99 n on the moon, where the acceleration of gravity is 1.62 m/s2. how much does she weigh on earth?

She weighs 599 N on Earth

Newton's gravitational law states that the force of attraction between two objects can be formulated as follows:

F = Gravitational Force ( Newton )

G = Gravitational Constant ( 6.67 × 10⁻¹¹ Nm² / kg² )

m = Object's Mass ( kg )

R = Distance Between Objects ( m )

Let us now tackle the problem !

Given:

weight of astronaut on the Moon = w_m = 99 N

acceleration of gravity on the moon = a_m = 1.62 m/s²

acceleration of gravity on the moon = a_e = 9.80 m/s²

Asked:

weight of astronaut on the Earth = w_e = ?

Solution:

She weighs 599 N on Earth
