Question

Two
point charges , q1=+19nC and q2= -4nC, are located on the x axis at
x=0 and x=8 m. What is the distance of zero electric field from the
positive charge ? Make your Answer four decimal places .

Answer #1

Two point charges,
q1=q1= 4.0×10-6 C and
q2=q2= -1.0×10-6 C,
are located on the x axis at x1 = -1.0 cm and
x2 = 3.0 cm.
(a) Determine the electric field at the origin.
b) Determine the x coordinate of a point on the positive x axis
where the electric field is zero; i.e., a test charge placed at
this point would experience no force.
(a) Determine the electric field at the origin.

Problem 4: Two point charges,
Q1 and
Q2, are located on the
x axis as follows. Q1
is at the origin and has a value of +24 µC. The charge
Q2 is at x = 4 meters
and its magnitude and sign are unknown. It is known that the net
electric field due to these two charges is zero at the coordinate x
= 8 meters. (k = 1/4πεo
= 9 x 109 Nt x

q1=-e at x=0 and q2=e at x=2a.
A- Find the work that must be done by
an external force to bring a third point charge q3=2e
from infinity to x=4a.
B- Find the total potential energy of the system of three
charges.

A positive point charge q1 = 3.0 μC is located at x = 0, y =
0.30 m, a negative point charge q2 = -3.0 μC is located at x = 0, y
= -0.30 m. A third point charge Q = 4.0 μC is located at x = 0.40
m, y = 0.

Three point charges are located on the x axis, q1 = -15.9µC at x
= 2.3cm, q2 = + 15.9µC at x = -1.2cm and q3 = -16.5µC at the
origin. Determine the net force (in Newtons) on charge q2. (Write
your answer to two decimal places)

Part A) Two particles with positive charges q1 and
q2 are separated by a distance s.
Along the line connecting the two charges, at what distance from
the charge q1 is the total electric field from the two charges
zero?
Express your answer in terms of some or all of the
variables s,
q1,
q2 and
k =14πϵ0. If
your answer is difficult to enter, consider simplifying it, as it
can be made relatively simple with some work.
Part B)...

Two equal positive charges q1 = q2 = 2.0µC
are located at x=0, y= 0.30m and x= 0, y= -0.30m. What are the
magnitude and direction of the net electric force that these
charges exert on a third point charge q3 = 4.0µC at
x=0.40m, y=0.

Q1 = +2.1µC and is located at (5, 0), Q2
= -8.4µC and is located at (0, -7), and Q3 = +6.5 µC and
is located at (-8, 6). A ball with a charge of QB =
+4.2µC is placed at the origin (0,0). (units of distance measured
in meters)
Sketch the setup and make an FBD for the ball.
Find the force from Q1 on the ball in component
form?
Find the force from Q2 on the ball in...

1. Two charges are fixed on the x-axis. The first charge, q1 =
+7.7 nC is located at x = 0. The second charge, q2 = -1.1 nC is
located at x = 0.25 m.
a) ( Is the force between these charges attractive or
repulsive?
b) What is the magnitude of the force?
c) In what region is the electric field most likely to be zero?
(1) to the left of q1, (2) between the charges, or (3) to...
