question 39

Multiple Choice

A proton moving eastward with a velocity of $5.0 \mathrm {~km} / \mathrm { s }$ enters a magnetic field of $0.20 \mathrm {~T}$ pointing northward. What are the magnitude and direction of the force that the magnetic field exerts on the proton? $\left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } \right)$

• A) \(1.6 \times 10 ^ { - 16 } \mathrm {~N}\) upwards
• B) \(4.4 \times 10 ^ { - 16 } \mathrm {~N}\) westwards
• C) \(0 \mathrm {~N}\)
• D) \(1.6 \times 10 ^ { - 16 } \mathrm {~N}\) downwards
• E) \(1.1 \times 10 ^ { - 16 } \mathrm {~N}\) eastwards
