How can I remove my Google account from iPad?

You presumably refer to removal of a Google Mail account from the iPad’s Mail App. If so, the account is very easy to remove:

Settings > Mail > Accounts > [Your Google Mail Account] > Delete Account

If you have some other “Google account” in mind, you’ll need to provide a lot more information about the problem that you are attempting to resolve.

I said the same thing earlier this morning.. My comment was removed 40mins ago, "because it was nontechnical or off-topic."🤔
