Consider a sphere of radius R which carries a uniform charge density `rho`. If a sphere of radius `R/2` is carved out of it,as shown, the ratio `(vecE_(A))/(vecE_(B))` of magnetic of electric field `vecE_(a)` and `vecE_(B)`, respectively, at points A and B due to the remaining portion is:

`21/34`

`17/34`

`18/34`

`18/54`
