Problem A10: In the figure above, there is a constant electric field given by
E = ( 5 i - 3 j ) J/C/M. The point a is at the origin (0,0), and the point b is
at the coordinates (n1,n2) meters in the x-y plane. What is n3 in
the expression for the potential difference between point a and point b :V(a)-V(b)=n3 J/C.
