Two Very Large Parallel Metal Plates, Separated By $0.20 \mathrm {~m}$

question 46

Multiple Choice

Two very large parallel metal plates, separated by $0.20 \mathrm {~m}$ , are connected across a $12 - \mathrm { V }$ source of potential. An electron is released from rest at a location $0.10 \mathrm {~m}$ from the negative plate. When the electron arrives at a distance $0.050 \mathrm {~m}$ from the positive plate, how much kinetic energy has the electron gained? $\left( e = 1.60 \times 10 ^ { - 19 } \mathrm { C } \right)$

• A) \(9.6 \times 10 ^ { - 19 } \mathrm {~J}\)
• B) \(4.8 \times 10 ^ { - 19 } \mathrm {~J}\)
• C) \(7.2 \times 10 ^ { - 19 } \mathrm {~J}\)
• D) \(2.4 \times 10 ^ { - 19 } \mathrm {~J}\)
