Could someone link me a reliable free iq test?

Nope, this is by definition not possible. IQ tests must always be taken with a licensed professional. They will never be free or online.

How important is to have a high iq for being a successful physicist?

Not important at all. It's a very dumb number which in no way implies your abilities as a physicist. If you want proof of that, read this book from the woman with the highest IQ: https://www.amazon.com/dp/0312106572/?tag=pfamazon01-20&tag=pfamazon01-20

Micromass is correct, real IQ tests are given by specially trained psychologists, the ones you find online are just games. And no one cares about IQ in the real world unless they are looking for learning disabilities, which is what they were designed for.
