The equation upper e equals startfraction 1 over 2 pi epsilon subscript 0 endfraction startfraction q ⁢ d over z superscript 3 endfraction is approximation of the magnitude of the electric field of an electric dipole, at points along the dipole axis. consider a point p on that axis at distance z = 23.00d from the dipole center (d is the separation distance between the particles of the dipole). let eappr be the magnitude of the field at point p as approximated by the equations below. let eact be the actual magnitude. what is the ratio eappr /eact?

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
