Homework Statement

What is the dependence of the stopping power on the charge of the material on which the charged particle enters?

I think that it is a trick question and that the answer is that given dependence does not exist. Could anyone tell me if I am right?

Could it be that the question is badly phrased?

Maybe ‘the charge’ is intended to mean ‘the charged particle’.

So the question should be:
What is the dependence of the stopping power on the charged particle, of the material which the charged particle enters?

Or, re-phrasing it:
What factors affect a material’s stopping power for charged particles of a given type/speed?

That would mean you are being asked to describe how a material’s electron density affects its stopping power. Or you could answer in terms of the material’s density, atomic weight, etc.
