Earth's Gravity

  1. Nov 5, 2015 #1
    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"?
