At which point (or points) is the electric field zero N/C for the two
point charges shown on the x axis?
4q
-2q x
A)The electric field is never zero in the vicinity of these charges.
B)The electric field is zero somewhere on the x axis to the left of
the +4q charge.
C)The electric field is zero somewhere on the x axis to the right
of the −2q charge.
D)The electric field is zero somewhere on the x
axis between the two charges, but this point is nearer to the −2q
charge.
E)The electric field is zero at two points along the x axis; one
such point is to the right of the −2qcharge and the other is to the
left of the +4q charge
An electron traveling horizontally enters a region where a
uniform electric field is directed upward. What is the
direction of the force exerted on the electron once it has
entered the field?
A)to the left
B)to the right
C)upward
D)downward
E)out of the page, toward the reader
E
electron
Five particles are shot from the left into a region that contains a uniform
electric field. The numbered lines show the paths taken by the five
particles. A negatively charged particle with a charge −3Q follows path
2while it moves through this field. Do not consider any effects due to
gravity. In which direction does the electric field point?
A)toward the top of the page
B)toward the left of the page
C)toward the right of the page
D)toward the bottom of the page
E)out of the page, toward the reader
Which path would be followed by a charge +6Q?
A)path 1
B)path 2
C)path 3
D)path 4
E)path 5
