Magnetic field?
1.) An atomic particle of charge +1.6×10−19C, travels at a speed of 3.0×106m s-1, in a plane perpedicular to a magnetic field 0.50T. If the radius of motion of the particle 6.27×10−2m, what is the mass of the particle ?
Give your answer in kg.
2.) Can you guess what kind of particle this is?
a.) Proton
b.) Neutron
c.) Electron

From the mass, this should be a proton. (In any case, the charge was given as positive - so neither electrons nor neutrons fit the bill)
Explanation:
The magnetic force here provides the centripetal force required for the circular orbit. Si
We can rewrite this to fond the mass:
