error CS0103 when I try to use Rigidbody2D

Hi,

So in my game when the player enters the linecast of the enemy i want the enemy to move towards him.

But I get this Assets/scripts/EnemyScript.cs(23,22): error CS0103: The name `GetComponenet' does not exist in the current context

It highlights:

 rb = GetComponenet<Rigidbody2D> ();

Full script:

 using UnityEngine;
 using System.Collections;
 
 public class EnemyScript : MonoBehaviour {
 
     bool seenPlayer;
     RaycastHit2D seePlayer;
 
     public Rigidbody2D rb;
 
 
     public Vector2 newPos;
 
     float maxSpeed = 10f;
     Animator anim;
 
     GameObject player;
 
 
     void Start()
     {
         anim = GetComponent<Animator> ();
         **rb = GetComponenet<Rigidbody2D> ();**
         player = GameObject.FindWithTag("Player");
     }
 
     void FixedUpdate()
     {
         //Just a debug visual representation of the Linecast, can only see this in scene view! Doesn't actually do anything!
         Debug.DrawLine(transform.position, newPos , Color.magenta);
 
         //Using linecast which takes (start point, end point, layermask) so we can make it only detect objects with specified layers
         //its wrapped in an if statement, so that while the tip of the Linecast (interactCheck.position) is touching an object with layer 'Guard', the code inside executes
         if(Physics2D.Linecast(transform.position,newPos, 8 << LayerMask.NameToLayer("Player")))
         {
             //we store the collider object the Linecast hit so that we can do something with that specific object, ie. the guard
             //each time the linecast touches a new object with layer "guard", it updates 'interacted' with that specific object instance
             Physics2D.Linecast(transform.position,newPos, 8 << LayerMask.NameToLayer("Player"));
             seenPlayer = true; //since the linecase is touching the guard and we are in range, we can now interact!
             if(seenPlayer == true)
             {
                 Debug.Log("worked");
                 rigidbody2D.velocity = new Vector2(1, rigidbody2D.velocity.y);
             }
         }
         else
         {
             seenPlayer = false; //if the linecast is not touching a guard, we cannot interact
         }
     }
 }
