A Proton Is Located at the Point $( x = 1.0 \mathrm {~nm} , y = 0.0 \mathrm {~nm} )$

question 57

Multiple Choice

A proton is located at the point $( x = 1.0 \mathrm {~nm} , y = 0.0 \mathrm {~nm} )$ and an electron is located at the point $( x = 0.0 \mathrm {~nm} , y = 4.0 \mathrm {~nm} )$ . Find the magnitude of the electrostatic force that each one exerts on the other. $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \mathrm {~N} \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 } , e = 1.6 \times 10 ^ { - 19 } \mathrm { C } \right)$

• A) \(5.9 \times 10 ^ { - 15 } \mathrm {~N}\)
• B) \(5.3 \times 10 ^ { 8 } \mathrm {~N}\)
• C) \(1.4 \times 10 ^ { - 11 } \mathrm {~N}\)
• D) \(5.3 \times 10 ^ { - 18 } \mathrm {~N}\)
