An electric dipole lies on the x-axis, consisting of a -3.0 nc charge at x = -12 cm and a +3.0 nc charge at x = 12 cm . compute the electric field at the point (–17 cm , 0). find the magnitude of the electric field.
compute the electric field at the point (0, –6 cm ). find the magnitude of the electric field.
express your answer to two significant figures and include the appropriate units.

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.
