Reset with the plane collision

My ball is called “Player” and my plane i want it to hit and reset is called “Plane”
Okay, Im having a major problem, Im new to unity and I have a game where you have to balance on this platform and i have a plane under it. Once the ball hits the plane i want it to reset. But I cant find any tutorials or any good scripts can i please have help.

In a script on the plane you have to respond to the OnCollisionEnter event:

public class PlaneResetter : MonoBehaviour
{
    public Vector3 BallStartLocation;

    private void OnCollisionEnter(Collision coll)
    {
         //If the collision is with the ball
         if (coll.gameObject.tag == "Ball")
        {
            //set the balls position to the starting location
            coll.transform.position = BallStartLocation;
        }
    }
}
