Does the force of attraction between them have to be higher than a certain number to be able to move with each other? How will the weight of the objects influence the process? Will they be moving with same speed and acceleration?

This is very, very hard to answer as-is. Are the two bodies in some sort of bound state? What type of force is holding them together? How are they initially moving? – Jerry Schirmer Sep 24 '12 at 21:52
They'll only move together if the force applied is less than that required to break the bond between the bodies. If you're using bolts, the force will need to be a lot stronger than if you're using gravity as the attraction (unless the bodies are really big). – hdhondt Sep 24 '12 at 23:54
Can you make your question a bit clearer. The other charged object moves in response to the forces acting on it, and if you move the first object these forces will change so the other object will move. To find out how it moves you need to write down an equation for the forces acting on it. – John Rennie Sep 25 '12 at 6:25

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, see the FAQ.

This is a basic electrical question. If both the bodies have opposite charge, they attract and move towards each other. If one is fixed, other move towards the fixed one. If both have same charge, they move away from each other. If one is fixed, other move away from the fixed one.
