Homework Statement
Homework Equations
The Attempt at a Solution
KE_{i} + PE_{i} = KE_{f}
2.4 x 10^{-19} + e(1) = KE_{f}
KE_{f} = 4.002 x 10^{-19} J
So option c would be correct, right? Thank you in advance.
No. The electron is repelled by the negative plate so its KE decreases when it moves from B to A.Homework Statement
