In a certain region, the electric potential due to a charge distribution is given by the equation V(x,y) = 2xy - x2 - y, where x and y are measured in meters and V is in volts. At which point is the electric field equal to zero?
 
  A) x = 0.5 m, y = 1 m
  B) x = 1 m, y = 1 m
  C) x = 1 m, y = 0.5 m
  D) x = 0.5 m, y = 0.5 m
  E) x = 0 m, y = 0 m

Question 2
