Answer #1

Charges of –1.0 μC and +1.0 μC are separated by 1.0 m with the
negative charge to the left of the positive charge. Another charge
of +2.0 μC can be placed at various positions near them. Find the
magnitude and direction of the force acting on the third charge for
the following situations.(a) Let the third charge be 1.0 m to the
right of the positive charge. (b) Let the third charge be 1.0 m to
the left of the...

Two charges are fixed on the x-axis. The first, Q1 =
5.230 nC, is placed at the origin. The second, Q2 =
8.026 nC, is placed at the point (6.00 m, 0 m). Determine the
x-coordinate where a third charge, Q3 = 4.730 nC, can be
place so that the net force on it is zero.

Two
identical small metal spheres initially carry charges 푞1and 푞2.
When they’re 1.0 m apart, they experience a 2.5-N attractive force.
Then they’re brought together so charge moves from one to the other
until they have the same net charge. They’re again placed 1.0 m
apart, and now they repel with a 2.5-N force. What were the
original charges 푞1and 푞2?

Point charges of 28.0 µC and 43.0 µC are placed 0.500 m
apart.
(a) At what point along the line connecting them is the electric
field zero?
How are the electric fields due to each charge related? How can you
put the two distances in terms of one distance? m (from the smaller
charge)
(b) What are the magnitude and direction of the net electric field
halfway between them?
magnitude
N/C

---Select--- toward the smaller charge toward the larger...

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 charge of 5.0 mC is placed at each corner of a square 1.0 m on
a side. Determine the magnitude and direction of the force on each
charge.
(please show your work)

Two negative and two positive point charges (magnitude Q = 3.51
mC ) are placed on opposite corners of a square as shown in the
figure (a = 0.170 m )
a.) Determine the magnitude of the force on each charge.
F1,F2,F3,F4
b.)Determine the direction of the force on each charge.

Two charges of 1.0 microcoulomb and -2.5 microcoulomb
respectively are held in place 4 millimeters apart. A third charge
of 1.7 microcoulomb is somewhere on the same line as two charges
but it experiences no force. Determine the location of the 1.7
microcoulomb relative to the 1.0 microcoulomb charge. A.) Write the
analytic for the force on the 1.7microcoulomb. B.) State explicitly
which concept is involved C.) Solve the equation in A and state the
solution

Two charges, -17 C and +5.3 C, are fixed in place and separated
by 3.9 m. (a) At what spot along a line through the charges is the
net electric field zero? Give the distance of the spot to the
positive charge in meters (m). (Hint: The spot does not necessarily
lie between the two charges.) (b) What would be the force on a
charge of +14 C placed at this spot? Limit you answer to 3
significant figures.

Two charges, -13 C and +3.0 C, are fixed in place and separated
by 3.8 m. (a) At what spot along a line through the charges is the
net electric field zero? Give the distance of the spot to the
positive charge in meters (m). (b) What would be the force on a
charge of +14 C placed at this spot?
