Question

For questions I -6, either indicate the correct aimer in the blank or select the answer which most correctly answers the question. These questions do not require calculations and you do t hove to show your work. Please clearly indicate your answers !! In the equation the symbol stands for Electric Field Electric Force Electric Flux Electric Energy Which two of the following units arc acceptable for Electric Field? N/C J/C V/C V/m For the distribution of charges shown below, draw a surface that includes at least one charge but which has a net flux of zero over the entire surface (Then a more than one possible correct answer but draw ONLY one). The graph shown to the right depicts the potential varies position for a region of space. For each region, indicate the nature of the electric field in that region either a) field is zero, b) field point to the right, or c) field points to the left. Region AB Region BC Region CD Region DE

Answer 1

1) E = F/q ................ E IS ELECTRIC FIELD

2) units for electric field    N/C and V/m

3) surface which has + 2q has net flux is zero

4) region AB - field points left ( slope is negative)

             BC- field zero ( slope is zero)

             CD- field is positive

         DE- field is negative
