Question
For the dipole shown in (Figure 1) , show that the electric field at points on the x axis points vertically downward.
Match the words in the left column to the appropriate blanks in the sentences on the right.
down
x
up
y
Place a point P on the positive x axis. At this point the electric field generated by the positive charge points BLANK and to the right, and the electric field generated by the negative charge points blank and to the left.
By symmetry these two electric fields have equal BLANK components and opposite BLANK components. We conclude that the total electric field points in the negative BLANK direction
PART TWO
What can you conclude about the sign and magnitude of Q? Explain your reasoning.
Match the words in the left column to the appropriate blanks in the sentences on the right.
toward Q
away from q
positive
toward q
away from Q
equal
unequal
negative
1. In order for the resultant field in the figure to exist, the electric field from charge Q must point BLANK meaning Q is BLANK .
2. The magnitude of Q must be BLANK to the magnitude of the field from q to produce the resultant electric field in the figure.
