Question

Two charges are fixed in place on the x-axis as shown. The
charge at *x* = 0 is **negative** and has
magnitude *q* = 2 μCoulombs (1 μCoulomb = 10^{-6}
Coulombs). The charge at *x* = *d*, (*d* = +12
cm), is **positive** and has magnitude *Q* = 4
μCoulombs. Find a point *x* = *x _{o}* along
the x-axis at which the electric field is zero.

*x _{o}* =____cm

Answer #1

Two positive point
charges are held fixed on the x-axis. Point charge
A is located at the origin, and point charge
B is located at the position x = −5.00 cm =
−5.00✕10-2 m (on the negative x-axis). The
magnitude of charge A is two times greater than
that of charge B: qA =
2qB.

(A.) The electric
force on charge A has magnitude 0.344 mN =
0.344⨯10-3 N. What is the electric force (magnitude
and...

Two point charges are fixed in place along the x axis
as shown in the figure above. The charge Q1=-3
μμC is located at the origin. The charge Q2=4
μμC is a distance a = 0.46 m to the right of the
origin.
1)
Calculate the x component of the
electric field at point P a distance
h=0.32 m above the origin.
Ex = -0.115 × 106 N/C
Ex = -0.094 × 106 N/C
Ex = 0.264 × 106 N/C...

A positive charge and a negative charge are placed on the
x-axis. Q1 = q is fixed at x=0 and Q2 = - 4q
is fixed at x = 4 cm. Where on the x-axis the electric field due to
these two charges is zero?

Initially two positive charges lie on the x-axis:
qA is at the origin and qB
is at (23.8 cm,0). The electric field created by these charges is
zero at (6.13 cm,0).
Now the charge on qA is reversed (from
positive to negative). Find the x-coordinate of the point
on the x-axis where the electric field is zero now, in cm. Your
answer must include the sign of the x-coordinate.
HINT: Which charge is larger?

Consider a positive charge q that is fixed at the origin (x = 0)
and a negative charge −3q that is fixed along the xaxis at the
point x = a. Calculate the electric field (magnitude and direction)
at the position(s) where the electric potential V = 0. (only find a
point on x-axis)

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...

(a) Two particles of fixed negative charge -q are placed on a y
axis at fixed positions of y = d and y = -d. (i) The electric field
is probed at a point, P positioned at x = ad on the x-axis, where a
is a variable. Illustrate and discuss the magnitudes and directions
of electric field components at point P and also illustrate the net
electric field at that point, of magnitude E. (ii) Starting from
the expression...

16.62.A positive point charge Q1 = 2.6×10?5 C is fixed at the
origin of coordinates, and a negative charge Q2 = ?5.7×10?6 C is
fixed to the x axis at x=+1.5m.
Part A Find the location of the place(s) along the x axis where
the electric field due to these two charges is zero.

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...

A positive point charge Q1 = 3.0×10−5 C is fixed at the origin
of coordinates, and a negative point charge Q2 = −5.4×10−6 C is
fixed to the x axis at x=+2.0m.
Find the location of the place along the x axis where the
electric field due to these two charges is zero.
