question 106

Multiple Choice

If an electron is accelerated from rest through a potential difference of $1500 \mathrm {~V}$ , what speed does it reach? $\left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } , m _ { \text {electron } } = 9.11 \times 10 ^ { - 31 } \mathrm {~kg} \right)$

• A) \(1.5 \times 10 ^ { 7 } \mathrm {~m} / \mathrm { s }\)
• B) \(2.3 \times 10 ^ { 7 } \mathrm {~m} / \mathrm { s }\)
• C) \(1.1 \times 10 ^ { 7 } \mathrm {~m} / \mathrm { s }\)
• D) \(1.9 \times 10 ^ { 7 } \mathrm {~m} / \mathrm { s }\)
