Question

A -11.5 nC point charge and a +23.0nC point charge are 14.5 cm
apart on the *x*-axis.

*x*-axis where the electric field is zero?

What is the magnitude of the electric field at the point on the
*x*-axis, between the charges, where the electric potential
is zero?

2. An AA battery...

A point charge q1 = 3.90 nC is placed at the origin, and a
second point charge q2 = -2.90 nC is placed on the x-axis at x=+
21.0 cm. A third point charge q3 = 2.00 nC is to be placed on the
x-axis between q1 and q2. (Take as zero the potential energy of the
three charges when they are infinitely far apart.)
a- What is the potential energy of the system of the three
charges if q3...

A point charge q1 = 3.90 nC is placed at the origin, and a
second point charge q2 = -3.10 nC is placed on the x-axis at x=+
20.0 cm . A third point charge q3 = 2.10 nC is to be placed on the
x-axis between q1 and q2. (Take as zero the potential energy of the
three charges when they are infinitely far apart.)
PART A: What is the potential energy of the system of the three
charges...

A
+5.50 nC point charge and a -3.00 nC point charge are 2.5 cm apart.
the electric field strength at the midpoint between the charges is
____ N/C.
the answer key lists the answer as 5.47x10^5. can someone
please explain how they got this answer. please do not answer if
you do not get 5.47x10^5 so i know where i went wrong.

A point charge q1 = 4.05 nC is placed at the origin,
and a second point charge q2 = -3.05 nC is placed on the
x-axis at x=+ 21.0 cm . A third point charge
q3= 1.90 nC is to be placed on the x-axis between
q1and q2. (Take as zero the potential energy of
the three charges when they are infinitely far apart.)
PART A - What is the potential energy of the system of the three
charges if...

A point charge q1 = 4.10 nC is placed at the origin, and a
second point charge q2 = -3.10 nC is placed on the x-axis at x=+
21.0 cm . A third point charge q3 = 1.90 nC is to be placed on the
x-axis between q1 and q2. (Take as zero the potential energy of the
three charges when they are infinitely far apart.)
Part A
What is the potential energy of the system of the three charges...

A -4.00 nC point charge is at the origin, and a second +8.00 nC
point charge is on the x-axis at x = 60 cm.
Find the net electric force that the two charges would exert on
a proton placed at x = 30cm?
At what location would the net electric field due to the two
charges be zero?

A point charge q1=4.20 nC is fixed at the origin. A second point
charge q2=−7.80 nC is fixed at the point x=15.0 cm.
(a) Find the point on the +x axis where the electric potential
is zero.
(b) A third charge, q3=−2.30 nC is then placed at the point
x=20.0 cm. Find the net force acting on charge q2 due to the other
two charges.

An 8 nC charge is at the position (3,0) and a -4 nC charge is at
(-4,0). Positions are given in m.

(0,-2)?
(b) What is the potential at the same position?
(c) At what point(s) on the x-axis does the electric field have
a magnitude of 0?
(d) At what point(s) on the x-axis is the electric potential
zero?
