<P> Subsequent mathematicians and physicists found the construct of the electric field to be useful for determining the electrostatic force on an electric charge at any point in space . The electric field was based on using a hypothetical "test charge" anywhere in space and then using Coulomb's Law to determine the electrostatic force . Thus the electric field anywhere in space is defined as </P> <Dl> <Dd> E → = F → q (\ displaystyle (\ vec (E)) = ((\ vec (F)) \ over (q))) </Dd> </Dl> <Dd> E → = F → q (\ displaystyle (\ vec (E)) = ((\ vec (F)) \ over (q))) </Dd> <P> where q (\ displaystyle q) is the magnitude of the hypothetical test charge . </P>
