● Two charges are in close proximity to one another. Describe electric field lines and the rules for diagramming field lines between two charges. Electric field lines are lines drawn on a diagram of charged particles indicating the direction of the flow of the field. The lines originate at a positive point charge and end at a negative point charge. They do not cross each other and the density of the lines indicates the strength of the electric field. ● The diagram shows the electric field due to point charge Q. Which statements are correct? Check all that apply. Charge Q is positive. If charge A moves toward charge Q, it must be a negative charge. The electric field is nonuniform. ● ● A +0.05 C charge is placed in a uniform electric field pointing downward with a strength of 100 . Determine the magnitude and direction of the force on the charge. 5 N downward ● The three diagrams show electric field lines around a pair of like charges. Which diagram shows a net force of zero on the charge placed at point X? C ● A point charge is placed 100 m from a 6 µC charge generating an electric field. What is the strength of the electric field on the point charge? (Round to the nearest whole number.) 5 N/C ● Inside a television picture tube there is a build-up of electrons (charge of 1.602 × 10–19 C) with an average spacing of 38.0 nanometers between electrons. Find the electric field inside the picture tube. (Round to three significant figures.) 997,000 N/C ● A source charge of 5.0 µC generates an electric field of 3.93 × 105 at the location of a test charge. How far is the test charge from the source charge? 0.34 m
