You have to define a One to Many relationship.

In the City model define a function that return a hasMany relation.

public function users(): HasMany
    {
        return $this->hasMany(User::class);
    }

In the User model define the inverse of this function

public function city(): BelongsTo
{
    return $this->belongsTo(City::class);
}

Don't forget to import

Illuminate\Database\Eloquent\Relations\BelongsTo;
Illuminate\Database\Eloquent\Relations\HasMany;

classes.

After that you are free to use this functions ex:

 $users = $city->users() //$city is an instance of City:class
