Following is the code you will use in order to assign and unassign categories from product

 //Object Manager instance
 $objectManager = \Magento\Framework\App\ObjectManager::getInstance();

//Product repository interface
 $productRepository = $objectManager->create('Magento\Catalog\Api\ProductRepositoryInterface');

//Load Product - assuming we have product id only
 $product = $objectManager->create('Magento\Catalog\Model\Product')->load( $product_id );

$category_id = '34'; //Replace category id here

$product->setCategoryIds( array($category_id) ); //It accepts array so we can add multiple category ids.

try {
 } catch (\Exception $e) {
 // Handle error

I hope this will help


Use below code to assign:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$CategoryLinkRepository = $objectManager->get('\Magento\Catalog\Api\CategoryLinkManagementInterface');

$category_ids = array('101','102');
$sku = '24-MB01';

$CategoryLinkRepository->assignProductToCategories($sku, $category_ids);

And below to remove:

  $objectManager = \Magento\Framework\App\ObjectManager::getInstance();

  $CategoryLinkRepository = $objectManager- >get('\Magento\Catalog\Model\CategoryLinkRepository');

  $categoryId = 101;
  $sku = '24-MB01';
