In this case, you need to take some steps to repair your relationship with your cat and help it re-establish trust in you.

The cat may need some time to calm down and process the experience of being beaten by you. Give it enough space, don't force it to interact with you, let it choose when to approach you. Be very gentle and patient when interacting with your cat. You can communicate with it in a soft voice and give it some favorite snacks to show your kindness and care.
