Ascientist is studying the effect on human health of bacteria that live in the human intestine. in her study, she found that the bacteria actually the body’s immune response. to develop scientific consensus about her idea, the scientist should contact a local reporter to share her ideas. publish her results in a peer-reviewed journal. advise other scientists that her experiment does not require replication. avoid sharing her research methods to see if other scientists obtain the same results on their own.

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you
