- Homework Statement
- There is a gravitational force between a particle and a uniform rod.
m is a mass of particle, M is a mass and L is a length of the rod. d is the distance between the head of the rod and particle.
If the d>>L, how does the equation for the gravitational force of the rod to a particle will be changed?
- Relevant Equations
- F = GmM/d(d+L)
At first, I thought when the rod goes really far away from the particle, then L would approach to zero in a particle's reference view. As a result, the equation will be GmM/d^2. However, I just thought that L just remain as it is regardless of change in d, but not sure...
