Kaplan Right Hand Rule

So I am going through the quiz bank that basically said this:

An electron is accelerated to the left. Magnetic field is oriented down the page so what direction is the force. The anser is out of the page, but I thought when you have an electron or negatively charged particle that the rule is switched and the force would go into the page.

Thoughts?

Thoughts?

Thumb = direction of velocity = LEFT
Fingers = direction of field = DOWN

Your PALM is now the force on a POSITIVE particle (P-P)
The BACK of your hand is now the force on a NEGATIVE particle

should go into the page as you said, can you post a picture? maybe we're both missing something

Just realized that it was about going into a gas with the same properties as "meta-material", which was mentioned in the passage. This meta material has negative refraction and therefore reverses the direction, meaning the force would indeed be out of the page. Thanks for clarifying what I initially thought though!
