Explanation / Answer

We know that :E= V/d

here d is the distance in the direction of the electric field
(a) Vb-Va = zero since the electric field is in the direction perpendicular to the distance AB so Va=Vb
(b) Vb-Vc = -E*40 = -1400*(4.0)/100 = -56 Volts
(c) Vc-Va = E* = 1400*(0.4)/100 = 56 Volts

d)Nope, because no reference potentials are stated.
