A Beam Consisting of Five Types of Ions Labeled A

question 34

Multiple Choice

A beam consisting of five types of ions labeled A, B, C, D, and E enters a region that contains a uniform magnetic field as shown in the figure below. The field is perpendicular to the plane of the paper, but its precise direction is not given. All ions in the beam travel with the same speed. The table below gives the masses and charges of the ions. Note: 1 mass unit = 1.67 × 10^-27 kg and e = 1.6 × 10^-19 C
-What is the direction of the magnetic field?

• A)toward the right
• B)toward the left
• C)into the page
• D)out of the page of the page
• E)toward the bottom
