Problem
Three points A, B and C lie on the same straight line through a positive point charge Q at distances 1 cm, 2 cm and 3 cm respectively from the charge. Which option gives the correct order of the magnitudes of the electric field strengths EA,EB and EC at these points?
(a) EC>EB>EA
(b) EA>EB>EC
(c) EA=EB=EC
(d) EB>EA>EC
