The object attached to the player does not rotate to the mouse when the player moves,Объект, вращающийся за мышкой, не вращается при движении объекта, к которому он прикреплён

When the player moves, the object attached to it does not rotate to mouse. The object is attached in this way: Rotation code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class scrTurrMg : MonoBehaviour
 {
     public Rigidbody2D rb;
     public Camera cam;
 
     Vector2 mousePos;
 
     void Update()
     {
         mousePos = cam.ScreenToWorldPoint(Input.mousePosition);
 
         Vector2 lookDir = mousePos - rb.position;
         float angle = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg;
         rb.rotation = angle;
     }
 
     void FixedUpdate()
     {
         
     }
 }

Motion code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class scrPlayer : MonoBehaviour
 {
     public float playerSpeed = 5f;
     public Rigidbody2D rb;
     public Camera cam;
 
     Vector2 movement;
     Vector2 mousePos;
 
     void Start()
     {
         
     }
 
     void Update()
     {
         movement.x = Input.GetAxisRaw("Horizontal");
         movement.y = Input.GetAxisRaw("Vertical");
     }
 
     void FixedUpdate()
     {
         rb.MovePosition(rb.position + movement * playerSpeed * Time.fixedDeltaTime);
     }
 }
