Question
In the region shown in the figure below there is an electric field due to a point charge located at the center of the dashed circle. The arrows indicate the magnitude and direction of the electric field at the locations shown.
a. What is the sign of the source charge? (1 submission) ---Select--- Positive Negative
b. At location B, represented by the green X on the diagram, the electric field has a value of
. Location B is located 0.142 m from the point charge placed in the center of the dashed line. Calculate the magnitude of this point charge.
C
d. Convert your answer from part C into nano coulombs.
nC
Explanation / Answer
a) charge is negative
b) E = kq/r2
that gives q = 4.7 x 10-9C
c) 4.7nC
