  What is the potential at a distance r= m from a point charge with q= \mu C ?

  Two charges, one with q1= \mu C and the other with q2= \mu C are separated by a distance of L= m . What is the potential midway between the two charges? Three charges are on the corners of an equilateral triangle whose sides are a= m long. The charges, are q1= \mu C , q2= \mu C and q3= \mu C . What is the potential at the red dot, the point at the center of the base of the triangle? Three charges are on the corners of a square whose sides are a= m long. The charges, are q1= \mu C , q2= \mu C and q3= \mu C . What is the potential at the empty corner of the square, pointed to by the red arrow?

  It takes \mu J of energy to carry a \mu C charge between two points. What is the potential difference between the two points?

  How much work is needed to move a charge of q= \mu C charge from ground to a point whose potential is V higher?

  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?

  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? 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?

  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?
