consider two thin unifromly charged concentric shells of radii r and 2r charges Q and -Q respectively , as shown. Three points A,Band C are marked at distances `r/2 , (3r)/2and (5r)/2` respectively from their common centre. If `E_(A) E_(B) and E_(C)` are magniudes of the electric fields at points A, Band C respectivly ,then
A. `E_(A)gtE_(B)gtE_(C)`
B. `E_(C)gtE_(B)gtE_(A)`
C. `E_(B)gtE_(A)=E_(C)`
D. `E_(B)gtE_(A)gtE_(C)`
