question 142

Multiple Choice

A proton is projected with a velocity of 7.0 km/s into a magnetic field of 0.60 T perpendicular to the motion of the proton. What is the magnitude of the magnetic force that acts on the proton? (e = $1.60 \times 10 ^ { - 19 } \mathrm { C }$ )

• A) \(13 \times 10 ^ { - 16 } \mathrm {~N}\)
• B) \(6.7 \times 10 ^ { - 16 } \mathrm {~N}\)
• C) \(0 \mathrm {~N}\)
• D) \(3.4 \times 10 ^ { - 16 } \mathrm {~N}\)
• E) \(4.2 \times 10 ^ { - 16 } \mathrm {~N}\)
