A Beam Consisting of Five Types of Ions Labeled A

question 10

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
-Determine the magnitude of the magnetic field if ion A travels in a semicircular path of radius 0.50 m at a speed of 5.0 × 10⁶ m/s.

• A)1.0 T
• B)0.84 T
• C)0.42 T
• D)0.21 T
• E)0.11 T
