By how much angle will the path of the proton be bent? (Hint: the particle comes out tangent to a circle.

A singly charged ion of mass m is accelerated from rest by a potential difference V. It is then deflected by a uniform magnetic field (perpendicular to the ions velocity) into a semicircle of radius R.

What is the ratio of the masses of the ions?
