Question

**Two particles A and B having charges 8×10−6C and
−2×10−6 respectively are held fixed with a separation of 20cm.
Where should a third charged particle C be placed so that it does
not experiences a net electric force**

Answer #1

Two tiny particles having charges of +7.00 μC and -9.00 μC are
placed along the y-axis. The +7.00-µC particle is at y = 0.00 cm,
and the other particle is at y = 40.00 cm. Where must a third
charged particle be placed along the y-axis so that it does not
experience any net electric force due to the other two
particles?

The charges and coordinates of two charged particles held fixed
in an xy plane are q1 = 2.74 μC,
x1 = 5.02 cm, y1 = 0.712 cm
and q2 = -3.79 μC, x2 =
-2.30 cm, y2 = 1.88 cm. Find the
(a) magnitude and (b) direction
(with respect to +x-axis in the range (-180°;180°]) of the
electrostatic force on particle 2 due to particle 1. At what
(c) x and (d) y
coordinates should a third particle of charge...

The charges and coordinates of two charged particles held fixed
in an xy plane are q1 = 3.09 μC,
x1 = 3.70 cm, y1 = 0.604 cm
and q2 = -5.45 μC, x2 =
-2.27 cm, y2 = 1.52 cm.
Find the (a) magnitude and (b)
direction (with respect to +x-axis in the range (-180°;180°]) of
the electrostatic force on particle 2 due to particle 1. At what
(c) x and (d) y
coordinates should a third particle of charge...

Two positively charged particles, each with charge Q, are held
at positions (-A, 0) and (A, 0) as shown in the following figure. A
third positively charged particle with charge q is placed at (0,
H). Find an expression for the net electric force on the third
particle with charge q. Show that the two charges Q behave like a
single charge 2Q located at the origin when the distance H is much
greater than A.

Two charge particles, +2q and -3q are on an axis at x = -10 and
x = 30 respectively. At one point, a third charged particle can be
placed such that the net force acting on it would be zero.
a) Calculate the location where the third charge should be
placed to create this situation?
b) Should the third charge be positive or negatively charged?
Explain your reasoning.

In the figure particles 1 and 2 are fixed in place on an x axis,
at a separation of L = 6.50 cm. Their charges are q1 = +e and q2 =
-64e. Particle 3 with charge q3 = +5e is to be placed on the line
between particles 1 and 2, so that they produce a net electrostatic
force F3 net on it. (a) At what coordinate should particle 3 be
placed to minimize the magnitude of that force?...

One dimension. In the figure, two point particles are
fixed on an x axis separated by distance d.
Particle A has mass mA and particle
B has mass 6.00 mA. A third particle
C, of mass 73.0 mA, is to be placed on
the x axis and near particles A and B.
In terms of distance d, at what x coordinate
should C be placed so that the net gravitational force on
particle A from particles B and C is...

Two particles having charges of 0.580 nC and 5.22 nC are
separated by a distance of 1.80 m . At what point along the line
connecting the two charges is the net electric field due to the two
charges equal to zero?Where would the net electric field be zero if
one of the charges were negative?

In this problem, consider electrostatic forces only. In the
figure, there is a particle of charge +Q at x = 0, and there is a
particle of charge +16Q at x = +4a. You are going to bring in a
third particle, with a charge of −4Q, and place it at an
appropriate spot on the x-axis. Use Q = 60.0 ✕ 10−6C, and a = 40.0
cm. Also, use k = 9.00 ✕ 109 N · m2/C2. (a)First, place...

Three charges A, B, and C, having charges +4.0x10^-4 C, -2.0x10^-4
C, +4.0x10^-4 C, respectively, are placed on the axis with a
separation of 2m between each adjacent pair.
