Question

Suppose you want to determine the electric field in a certainregion of space. You have a small object of known charge and aninstrument that measures the magnitude and direction of the forceexerted on the object by the electric field.

(a) The object has a charge of +30.0 C and theinstrument indicates that the electric force exerted on it is 40.0N, due east. What are the magnitude and direction of theelectric field?

E = CN/CNJdue southdue westdue northdue east

(b) What are the magnitude and direction of theelectric field if the object has a charge of -25.0 C and theinstrument indicates that the force is 35.0 N, due west?

E = NJCN/Cdue eastdue westdue southdue north

Explanation / Answer

(a)     the magnitude of the electric field will be     E = F / q        = ......... N / C     the direction is due east (b)    the magnitude of the electric field will be    E = F / q       = ......... N / C     the direction is due east
