Question

A planet has a mass 0.051 times the mass of Earth and a diameter of about 0.160 times the diameter of Earth. What is the acceleration of a body falling near the surface of this planet

Answer 1

Gravity on planet is 2 times earth gravity

Step-by-step explanation:

Grav force = G m1 m2 / (r^2) now change m1 and r

= G .051m1 m2 / ( .16 r)^2

= .051 /.0256 G m1 m2 / r^2

.051 /.0256 = ~ 2
