Instructiоn: Input numericаl vаlues оnly; nо unit.  Keep two decimаl points for your numerical answer. Example: -3.14,  -314.51, 3.14, 314.51 There is a uniform electric field of magnitude [E] N/C that points in the +y direction (upward). Point a is located at (x, y)=(0, +[y] m) and point b is located at (x, y) = (-1 m, 0). What is the potential difference between point b and point a, Vb-Va? Express your answer in Volt.
