can you force a stalemate?

@1
No

but i think if the king cant move

you can sacrifice all your pieces

Yes, in certain positions, it may be possible, but you have to have the right material to force the capture of your pieces and still maintain the stalemated king position.

Yes, in certain positions it is possible. E.g.

If white promotes to a queen, then black forces stalemate.

Can you write this in Hindi?

Yes, but it's very rare. The term "force stalemate" is a bit misleading. In the examples so far they are one move forced stalemates. All the moves leading up to that are optional, not forced. 

In a forced checkmate, ANY response still results in checkmate. That's not true with almost all stalemates. In most stalemates they are not forced but are obviously preferrable to losing. 

I do so fairly often.
