- Homework Statement
- A test object of mass m is placed at the origin of a two dimensional coordinate system. An object 1, of the same mass, is at (d, 0), and an object 2, of mass 2m, is at (-d, l). What is the magnitude of the vector sum of the gravitational forces exerted on the test object by the other two objects?
- Relevant Equations
- F(gravity) = G * (M * m)/ (r^2)
G = 6.6738 * 10^-11 N * m^2
I suppose we can just find the net x components and y components and then go from there.
Σ Fx = F(mass 1) - Fx(mass 2)
G* (m^2)./d^2) - something
I'm not sure how to express the component forces of the 2nd mass
