 [8] An electron is moving parallel to the x-axis with an initial speed of v0= m/s at the origin. The velocity of the electron after it moves d= m is v= m/s . What is the potential difference between the origin and the point at d?

 [9] A q1= \mu C and a q2=- \mu C charge are placed d= m apart. At what points along the line joining them is the potential zero?

 [10] Two large parallel conducting plates are d= m apart and have equal, but opposite charges on their facing surfaces. An electron anywhere in the region between the plates feels a force of F= N acting on it. What is the electric field between the plates, and what is the potential difference between the plates?
