Gold ions (Au+) are accelerate to high speeds using electric fields.

These ions are then passed through a region where uniform electric E and magnetic B fields are present.

If the ions are traveling to the right, which configuration of E and B will serve as a velocity selector?

A. Electric field E up; Magnetic field B into the page

B. Electric field E down; Magnetic field B out of the page
C. Electric field E up; Magnetic field B out of the page
D. Electric field E down; Magnetic field B into the page
E. Both A and B
F. Both C and D

G. All of the above
