question 65

Multiple Choice

An electron is known to be confined to a region of width $0.10 \mathrm {~nm}$ . What is an approximate value for the least kinetic energy it could have, in electron-volts? $\left( h = 6.626 \times 10 ^ { - 34 } \mathrm {~J} \cdot \mathrm { s } , 1 \mathrm { eV } = 1.60 \times \right.$ $10 ^ { - 19 } \mathrm {~J} , \left( m _ { \text {electron } } = 9.11 \times 10 ^ { - 31 } \mathrm {~kg} \right.$ )

• A) \(1.1 \mathrm { eV }\)
• B) \(17 \mathrm { eV }\)
• C) \(8.8 \mathrm { eV }\)
• D) \(0.88 \mathrm { eV }\)
• E) \(3.8 \mathrm { eV }\)
