Suppose you want to determine the electric field in a certain region of space. You have a small object of known charge and an instrument that measures the magnitude and direction of the force exerted on the object by the electric field.(a) The object has a charge of +40.0 ?C and the instrument indicates that the electric force exerted on it is 35.0 ?N, due east. What are the magnitude and direction of the electric field?
(b) What are the magnitude and direction of the electric field if the object has a charge of -10.0 ?C and the instrument indicates that the force is 35.0 ?N, due west?

ANSWER

Force on a charge=magnitude of charge * electric field
magnitude of electric field=35/40=.875 NC
direction of force is same as direction of electric field is charge is positive . so direction of electric field is east


b)magnitude =35/10=3.5NC
direction of force is opposite direction of Electric field is chargeis negative . so field is in east direction
