#### Answer

Following are the procedures: 1. A positive test charge placed at the point in space and thus measuring the force. 2. Use $E= \frac{F}{q}$ to get the magnitude of electric field. 3. Direction of field will be the same as the direction of the motion of $q$ since, $q$ is positive. Thus, as the test charge is positive, the direction of electric field will be in the direction of force on it.
