question 5

Multiple Choice

Two electrons are $20.0 \mathrm {~mm}$ apart at closest approach. What is the magnitude of the maximum electric force that they exert on each other? $\left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } , k = 1 / 4 \pi \varepsilon _ { 0 } = 9.010 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } \right)$

• A) \(5.8 \times 10 ^ { - 27 } \mathrm {~N}\)
• B) \(2.3 \mathrm {~N}\)
• C) \(2.3 \times 10 ^ { 10 } \mathrm {~N}\)
• D) \(5.8 \times 10 ^ { - 25 } \mathrm {~N}\)
