How Do Particles Relate to Rigid Bodies in Different Scientific Contexts?

[Tiven white]

Homework Statement

Concentrated forces are to distributed forces as particles are to
A. Objects
B. Rigid bodies
C. Planets
D. Solids

Homework Equations

The Attempt at a Solution

I say B I have looked up the definition of a rigid body and it seems a particle can be considered a rigid body in statics/mechanics due to the fact that there is no deformation in both when forces are applied

Sounds right to me, although my reasoning is different than yours.

Would u enlighten me on your reason

I'm looking at it purely as an "is like" problem. I see a concentrated force as localized and a dispersed force as spread out and I see a particle as very local and a rigid body as spread out. I don't see any need to consider deformation. BUT ... that's just the way I look at it. Your analysis might be better.
