An a - particle and a proton are moving in a plane of paper in a region where there is uniform magnetic field (B)  directed normal to the plane of the paper. If the two particles have equal linear momentum, what will be the ratio of the radii of their trajectories in the field?

Radius of the charged particle in a uniform magnetic field(r)=mv/qB=P/qB-------(1)
 
As the momentum and magnetic field is same the radius will depend on the charges of the particles .
 
r1/r2=q2/q1

The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
