Question 64

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?

A

The kinetic energy of the ions is different for each isotope.

B

The speed of the ions is the same for both isotopes.

C

The radius of the path in the magnetic field is different for each isotope.

D

The force exerted by the magnetic field on the ions is the same for both isotopes.
