We have two stationary point charges q1=3.6e-6 C and q2=6.0e-6 C, seperated by 0.50 m.
a) What is the potential energy for an electron at the midpoint between the charges?
b) Toward which charge will the electron want to go? (why?)
c) When the electron is 0.009 m away from that charge what is its potential energy?
d) If the electron was at the midpoint, what is its velocity in part c?
