I have a question regarding the Eddington limit. My question is, an object with any mass has luminosity greater than the Eddington limit. What will happen to a small particle in the nearby region of the object?

I believe the small particle will be pushed away by radiation force because it will overpower the gravitational forces pushing it inward, but I am not sure. Any help greatly appreciated, thank you.

Yes, that is precisely why it's called the Eddington limit. When it is exceeded, the star (or whatever) will shed its outer layers since the radiation force exceeds the gravitational force. Any nearby particles would suffer the same fate.
