magnetic field, as shown in the diagram (not to scale). The field is into the page on the diagram. Because

the electron is less massive than the proton and because the electron is negatively charged and the proton

is positively charged :-

(A) the electron travels clockwise around the smaller circle and the proton travels counterclockwise

around the larger circle

(B) the electron travels counterclockwise around the smaller circle and the proton travels clockwise

around the larger circle

(C) the electron travels clockwise around the larger circle and the proton travels counterclockwise around

the smaller circle

(D) the electron travels counterclockwise around the larger circle and the proton travels clockwise around

the smaller circle
