Question

Electric Fields Problem Statement A 5.0-4C point charge is placed at the 0.00 cm mark of a meter stick and a 4.0-point charge is placed at the 50 cm mark. At what point on a line joining the two charges is the electric field due to these charges equal to zero? . Visual Representation . Draw a sketch of the charge distribution Establish a coordinate system and show the locations of the charges. Identify the point P at which you want to calculate the electric field. • Draw the electric field of each charge at point P. • Use symmetry to determine if any components of Ēne are zero. . Mathematical Representation For each charge, determine its distance from P and the angle of Ē Determine the field strength of each charge. Write each vector in component form. Sum the vector components to determine Enet Check result for correct and that it is reasonable. . .
