At two nearby positions P and Q in a region of space the following is observed: six electric field lines pass through a small imaginary square of area 1cm2 placed at P, while only two lines pass through an identical square at Q. The squares are oriented perpendicular to the field lines. Which one of the following is the correct ratio of the magnitudes of the electric fields EP:EQ at the two points?
a) 1:3
b) 6:1
c) 3:1
d) 4:1
