Gravitational Effect of Uniform Mass on Earth's Surface

[Jaller1404]

Hey guys!

What would be the gravitational effect of Earth on it's surface, if somehow the density of mass was uniform and equal to 2/5 of the real value? Assuming that the size e shape os the planet doesn't change.

Welcome to PF!

Have you Googled the equation for gravitational force? What does it tell you?

Actually, do you think I should use the equation for gravitational force or the equation for gravitacional field?

I guess it depends on what you are asking - it isn't clear to me what you want to know. What is "gravitational effect"?

Analising the question again, I realized that it's Force. Ty for the help o/
