Question

the volume of the red planet is 0.1 times of earth and its radius is 1/2 that of earth,compare the acceleration due to gravity on the planet's surface to that of the earth plz give me ans


i will mark u as a brainlest and follow u
but i did not need unnecessary ans ​

Answer 1

Answer:

the ratio of g is 2:5

Explanation:

g=Gm/r2

d=m/v

m=d×v

g=k(v)/r2

let volume of earth =x

volume of red planet=0.1x

radius of earth =r

radius of red planet = r/2

g red =k 0.1x/(r2/4)

g earth=k x/(r2)

g red/g earth = 0.4/1

=2/5
