Not detecting collision

Hello im trying to make the roll a ball game but it does not collect the collectible instead goes through it this is the code im using and also i have checked the "istrigger" still its not being collected.

public class PlayerController : MonoBehaviour {

 private Rigidbody rb3d;
 public int speed;
 private void FixedUpdate()
 {
     float moveh = Input.GetAxis("Horizontal");
     float moveV = Input.GetAxis("Vertical");
     Vector3 movement = new Vector3(moveh, 0.0f, moveV);

     rb3d.AddForce(movement * speed);
 }
 private void Start()
 {
     rb3d = GetComponent<Rigidbody>();
 }
 void OnTriggerEnter2D(Collider2D other)
 {
     if (other.gameObject.CompareTag("Coin"))
     {
         other.gameObject.SetActive(false);
     }
 }

}
