How to turn on the gravity of multiple objects with the same tag after collission?

So I know I cannot grab the transform of a game object but here is the Code I currently have. I want to to turn on gravity from the rigidbody for all of these objects with the same tag. Any Ideas? I am thinking I will have to use arrays but I may be wrong.
Code is (JS)

var Camerashake : Camerashake;//script 
var rumblesound : AudioSource;
var rumblesoundstop : AudioSource;
var stalagtite = GameObject.FindGameObjectsWithTag ("Fracture1");
function Start () {


function Update () {


function OnTriggerEnter (other : Collider) {	 //T
	if (other.gameObject.CompareTag ("Player")){
	stalagtite.rigidbody.useGravity = true;
	Camerashake.enabled = true;
	yield WaitForSeconds(9) ;

Take a look at the answer I posted in this link:

It will work the same for you.

Actually I should of been more precise, this is a group of children on an object, so I just created a specific script on the parent and used this code under function start:

Codes is JS:

for (var child : Transform in transform) {
child.rigidbody.useGravity = true ;}

Then I can just turn on that script after hitting the collider and it will apply gravity to all objects.
