How Is the Net Gravitational Force Calculated in a Triangular Particle System?

Click For Summary
SUMMARY

The net gravitational force on one particle in a triangular particle system, consisting of three identical spherical particles of mass m at the corners of an equilateral triangle with edge length r, is calculated using the formula Fg = √3 Gm2/r2. This formula derives from the gravitational forces between each pair of particles and the vector summation of these forces. The gravitational force between each pair must be determined and then combined geometrically to find the resultant force acting on a single particle.

Homework Statement



Three identical spherical particles of mass m are each located at the corners of an equilateral triangle with edge length r (each sphere is centered at each corner). Show the magnitude of the net gravitational force on anyone of the particles due to the other two particles is given by:

Homework Equations



Fg = sqrt(3) Gm^2/r^2

The Attempt at a Solution



Again... had no idea where to start.

what's the gravitational force between each pair? and then sum the 2 vectors (i.e, 2 forces acting on 1 particle) using geometry to find the magnetude of the force.
