Pulling multiple objects

Since I am not getting responses, even requests for clarification, I guess I did a bad job asking the question. Any help, even a request to clarify would be greatly appreciated. For background I am doing this abacus to help out a friend who is doing his Masters in Education. I also wanted a project that I could learn Unity with. This simple app seemed like a great place to start.

I am attempting to create an abacus. I have a script that will drag a bead around just nicely. When the bead that I am dragging around comes into contact with another bead they both move but at a snails pace. How do I get the combined beads to continue to move at the same speed as a single bead?

I am using RigidBody2D, and BoxCollider2D along with a SliderJoint2D on each of the beads. The SliderJoint2D starts off not having a Connected Rigid Body.

Here is the movement script that I have been using.

 using UnityEngine;
 using System.Collections;
 
 public class DragBead2 : MonoBehaviour {
 
     private SliderJoint2D slider;
 
     void Awake()
     {
         // "slider" is the SliderJoint2D component that I added to my object
         slider = this.gameObject.GetComponent<SliderJoint2D>();
 
         // I want the anchor position to start at the object's position
         slider.connectedAnchor = gameObject.transform.position;
     }
     
     void OnMouseDown()
     {
         // I'm reactivating the SliderJoint2D component each time I'm clicking on my object 
         // because I'm disabling it after I'm releasing the mouse click so it will fly in 
         // the direction i was moving my mouse
         slider.enabled = true;
     }
     
     void OnMouseDrag()        
     {
         if (slider.enabled == true) 
         {
             // Getting cursor position
             Vector2 cursorPosition = Camera.main.ScreenToWorldPoint (Input.mousePosition);
             
             // The anchor get's cursor's position
             slider.connectedAnchor = cursorPosition;              
         }
     }
     
     void OnMouseUp()        
     {
         // Disabling the slider component
         slider.enabled = false;
     }
 }

Any help is greatly appreciated. As a side note this script is a modified version of a script I found on here (sorry but I cannot remember whose it was originally).

Thanks in advance.
