## Question

###### The figure shows a graph of electric potential versus position along the $x$ -axis. An electron is originally at point $A$, moving in the positive $x$ -direction. How much kinetic energy does it need to have at point $A$ in order to be able to reach point $E$ (with no forces acting on the electron other than those due to the indicated potential)? Points $B, C$, and $D$ have to be passed on the way.
