Problem
Two points, P and Q, lie in a region of space where the electric field is represented by equally spaced field lines. At point P the perpendicular spacing between adjacent lines is 2.0mm, while at point Q it is 5.0mm. Assuming the field lines are drawn using the same scale everywhere, what is the approximate ratio EP/EQ of the magnitudes of the electric field at P and Q?
(a) 0.40
(b) 2.0
(c) 2.5
(d) 6.25
