A charged object sits at the origin, generating an electricfield Eo a distance d away. If the distance is doubled to $2$d$,$the electric field:$($a$)$ stays the same;$($b$)$ has the same magnitude but a different direction;$($c$)$ drops to Eo$/2$;$($d$)$ drops to Eo$/4$;$($e$)$ increases to $2$Eo$.$
