Question

b. Based on the diagrams for electric field lines, draw a diagram with electric field lines for +3C charge. c. Is there an electric field at points in space where there are no electric field lines drawn? Explain. d. Use the EM field program to draw electric field lines for different configurations of charges. In the EM field program, how do you tell where the field is strongest? How do you tell where the field is weakest? Explain. How do you tell the direction of the field? Explain. f. Below is the electric field line diagram for two charges, +2C and -2C drawn in the electric field program (Drawn in EM Field by D. Trowbridge and B. Sherwood, Physies Academic Software, 1998)

Explanation / Answer

(c) The electric field is present everywhere around the charge. The field lines are drawn just as representation.

(d) The field strength is proportional to the density of lines in the region. More lines mean the field is strong, fewer lines mean the field is weak.

(e) The electric field is always directed from the positive charge to the negative charge.
