Two positive charges of 1.6e-10 C are placed on the x axis at
distances +40 cm and -40 cm from the origin, respectively. A third
positive charge of 3.5e-11 C can be moved along the y axis. At what
value of y the electrostatic force on the third charge is
maximal?

Three charges lie along the x-axis. One positive charge, q1 = 25
uC is at x = 0.25 m. Another charge, q2 = -5.0 uC, is located at
the origin. A third charge, q3 = -35 uC, is placed so that q2 is in
electrostatic equilibrium with q1 and q3. How large must the
electrostatic force between q2 and q3 be to balance the force
between q1 and q2?

Two point charges of magnitude -9.00 µC and -4.00 µC are placed
along the x-axis at x=0 cm and x=40.0 cm respectively. Where must a
third charge q be placed along the x-axis so that it does not
experience any net force between the other two charges? Please show
work!

the two-point charges of magnitude +3.00μC and -5.00μC are
placed along the x axis at x = 0cm and x = 40cm respectively. Where
must the third charge, q, be placed along the x axis so that it
does not experience any net force because of the other two
charges?

Three point charges are fixed on the x-axis: 6.0×10−6 C at x =
−0.29 m, −4.0×10−6 C at the origin, and 4.9×10−6 C at x = 0.77 m.
Find the electrostatic force acting on the charge at the origin due
to the other two charges. Let a positive value indicate a force in
the positive x direction, and a negative value indicate a force in
the negative x direction. Answer in N.

1, Two charges are placed on the x axis. One of the charges (q1
= +8.09C) is at x1 = +3.00 cm and the other (q2 = -21.5C) is at x2
= +9.00 cm. Find the net electric field (magnitude and direction
given as a plus or minus sign) at (a) x = 0 cm and (b) x = +6.00
cm.
2. Two charges, -22 C and +3.5 C, are fixed in place and
separated by 3.0 m. (a) At...

Positive charge A of charge 0.1mC is placed at the origin of
axis x, charge B, also positive, but of magnitude 4 times greater
than A is placed at x=20.0 cm. These charges if released will run
away from each other, but they are kept in place by the third
charge positioned somewhere on the axis x. Find the value of this
third charge (in mC).

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.

Three charges line along the x-axis. The positive charge
q1 = 15x10-6 C is at x=2.0m and the positive
change qs= 6.0uC is at the origin. Where must the
negative charge q3 be placed on the x-axis so that the
resultant electric force on it is zero? Round to 2 significant
figures.

Consider charges placed along an x-axis. If a charge of +17 nC
is placed at x = 0.00 m and a charge of +30 nC is placed at x =
1.00 m, where would a third charge of -14.0 nC be in electrostatic
equilibrium?
