question 75

Multiple Choice

In a certain cyclotron, a proton of mass $1.67 \times 10 ^ { - 27 } \mathrm {~kg}$ moves in a circle of diameter 1.6 m with an angular speed of $2.0 \times 10 ^ { 6 } \mathrm { rad } / \mathrm { s }$ what is the angular momentum of the proton?

• A) \(1.8 \times 10 ^ { - 21 } \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
• B) \(3.2 \times 10^{-21} \mathrm{~kg} \cdot \mathrm{m}^{2 / \mathrm{s}}\)
• C) \(1.3 \times 10 ^ { - 2 } \mathrm {~kg} \cdot \mathrm { m } 2 / \mathrm { s }\)
• D) \(2.1 \times 10 ^ { - 21 } \mathrm {~kg} \cdot \mathrm { m } ^ { 2 } / \mathrm { s }\)
