HoMEWORK FOR LAB 2: ELECTRIC FIELDS, FLUx AND GAUSS' LAW 1. Describe the properties of electric field lines. If the total number of lines leaving or converging on a charge doubles, a. what does that tell you about the magnitude of the charge? b. What does the direction of a line at each point in space represent? c. What does the density of lines represent? Based on your observations of electric field lines in this lab, sketch several electric field lines originating from the +q charge. Then sketch how many ines would originate from a charge of +3q. (Note that your sketches don't need to be exactly correct, but they should illustrate that you understand the properties of electric field lines discussed in Question 1.) 2. 3q 3. For situations a through e, use the definition of flux that you developed in Activity 1-3 to determine the electric flux passing through each surface. The elec- tric field has magnitude 5.0 N/C at the location of the surface of area of 1.5 cm2. Show your calculations. b. d. LAB 2: ELECTRIC FIELDS, FLUX AND GAUSS' LAW

Explanation / Answer

Ans 1)

a) Number of lines is directly proportional to charge. So if number of lines doubles implies that charge is also doubled

b)Tangent to line at any point gives direction of electric field at that point

c)More the density of lines higher is the electric field
