Question

What would be the weight of a 59.1-kg astronaut on a planet twice as massive as Earth and having twice Earth's radius

Answer 1

29.55 kg

Step-by-step explanation:

force gravity = G m1 m2 / (r^2) now change the mass 1 and the r

= G 2m1 m2 / ( 2r)^2

= 2/4 G m1 m2 / (r^2)

the weight will be 2/4 or 1/2 the original
