    High School Gravitation with multiple objects by using center of mass

    Yeah, that's how I got the right answer. I was just curious about why using center of mass didn't work. Thanks, though!

    High School Gravitation with multiple objects by using center of mass

    I didn't forget, I just calculated that after and added to the number I found. Both times I tried to solve the problem, that value was the same, so I figured my error was with using the center of mass for the bottom left and top right spheres. Thanks!

    High School Gravitation with multiple objects by using center of mass

    Four 9.5 kg spheres are located at the corners of a square of side .60 m. Calculate the magnitude and direction of the total gravitational force exerted on one sphere by the other three. So, essentially my question is, why can I not use center of mass of the other 3 spheres to calculate the...
