Errors..
1) Tense :- the sentence talks of a fact so requires 'simple present' and not 'present perfect'. Therefore HAS is wrong at both places.
2) placement of ONLY - ONLY should be used next to item that is to be limited. Here it is 1/10000 of the atoms volume, so should be just ahead of it ... Only 1/10000...

E corrects both errors
