[1]  What is the potential at a distance r= m from a point charge with q= \mu C ? 
[2]  Two charges, one with q_{1}= \mu C and the other with q_{2}= \mu C are separated by a distance of L= m . What is the potential midway between the two charges? 
[3]  Three charges are on the corners of an equilateral triangle whose sides are a= m long. The charges,
are q_{1}= \mu C , q_{2}= \mu C and q_{3}= \mu C . What is the
potential at the red dot, the point at the center of the base of the triangle?

[4]  Three charges are on the corners of a square whose sides are a= m long. The charges,

potential at the empty corner of the square, pointed to by the red arrow?

[5]  It takes \mu J of energy to carry a \mu C charge between two points. What is the potential difference between the two points? 
[6]  How much work is needed to move a charge of q= \mu C charge from ground to a point whose potential is V higher? 
[7]  A charge with q= C and mass m= kg is accelerated from rest through a potential difference of V= Volts . What is its final speed? 
[8]  An electron is moving parallel to the xaxis with an initial speed of v_{0}= 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?
