A beam consists of singly-ionised atoms of two isotopes of an element. The ions are accelerated from rest through the same potential difference before entering a region of uniform magnetic field perpendicular to their direction of motion, where they travel in circular paths.
Which statement is true?
The kinetic energy of the ions is different for each isotope.
The speed of the ions is the same for both isotopes.
The radius of the path in the magnetic field is different for each isotope.
The force exerted by the magnetic field on the ions is the same for both isotopes.
