Two electrons are fixed 2.00 centimeters apart. Another electron is shot from infinity and comes to rest midway between the two fixed electrons.
A. Find the initial energy of the system (that is, just as the electron is shot from infinity). The speed of the electron is an unknown quantity, so leave it as a variable, Vo.
B. Find the final energy of the system (if there is an unknown quantity, leave it as a variable).
C. Find the initial speed of the electron.
