--- Quote from: Tyserius on November 14, 2009, 01:56:20 pm ---The answer is definitely C. First case is that beta particles cannot pass through aluminium, 2nd is that in an electric field beta particles deviate more as they have the lowest mass (newtons law). Third is in a magnetic field electrons (beta particles) would deflect at an angle more than right angle. So it's definitely C. Need not check the past year papers. It isn't a repeating question.

I don't know which answer is this but the answer was the one that started with "M"
What did you guys get for the Diffraction Maxima (I got D which was 15) and the Oil suspended one?

Yeah i think the answer for that beta, alpha, gamma question was C. I can't remember that diffraction question, and for the oil droplet i can't remember what i put :D. If you explain that diffraction question a bit more i might be able to remember ;).
