Question

Four particles each
have a positive charge of 6.00 x 10^{-16} C. The charges
are arranged on the four corners of a square that is 25.0 cm on a
side. What is the net force experienced by the particle located on
the bottom-left corner of the square?

Answer #1

There are four charges, each with a magnitude of 1.91 μC. Two
are positive and two are negative. The charges are fixed to the
corners of a 0.266-m square, one to a corner, in such a way that
the net force on any charge is directed toward the center of the
square. Calculate the magnitude of the net electrostatic force
experienced by any charge.

There are four charges, each with a magnitude of 2.18 µC. Two
are positive and two are negative. The charges are fixed to the
corners of a 0.21-m square, one to a corner, in such a way that the
net force on any charge is directed toward the center of the
square. Find the magnitude of the net electrostatic force
experienced by any charge.

It is placed at the corners of four charged particles,
a square with side lenght d. Particle 1,2 and 4 carry identical
positive charges. The electrical forces exerted on particle 1 What
is the charge of particle 3 in the corner opposite to particle 1 so
that the vector sum is zero?

Three point charges are arranged so that they each lie on the
vertex of what appears to be an equilateral triangle of side length
1 cm. At the bottom, the two charges are the same (from left to
right), each having charge +10 nC (nanoCoulomb). At the vertex on
the top, the charge there is (-)20 nC (it's a negative charge).
Find the magnitude and direction of the net electric force on the
top charge due to the bottom two.

Four point charges have the same magnitude of 2.0 ×
10-12 C and are fixed to the corners of a square that is
2.8 cm on a side. Three of the charges are positive and one is
negative. Determine the magnitude of the net electric field that
exists at the center of the square.

Three particles of charges, q1 =
+7.0μC, q2 = +7.0μC and
q3 = -7.0μC are located at the corners
of an equilateral triangle of side 20.0 cm. Calculate the magnitude
of the net force acting on the negatively charged particle.

Three equal positive point charges of magnitude Q = 9.00μ C are
located at three corners of a square of edge length d = 8.1 cm. A
negative charge -27.00μ C is placed on the fourth corner. At the
position of the negative charge, what is the magnitude of the
electric field due to the three positive charges?
What is the magnitude of the attractive force on the negative
charge?

Four point charges are located at the corners of a square. Each
charge has magnitude 1.70 nC and the square has sides of length
2.40 cm. Find the magnitude of the electric field (in N/C) at the
center of the square if all of the charges are positive and three
of the charges are positive and one is negative.

Four point charges are located at the corners of a square. Each
charge has magnitude 3.50 nC and the square has sides of length
3.20 cm. Find the magnitude of the electric field (in N/C) at the
center of the square if all of the charges are positive and three
of the charges are positive and one is negative.
(a) all the charges are positive N/C
(b) three of the charges are positive and one is negative
N/C

Four identical particles, each having charge q=28 micro coulomb
, are fixed at the corners of a square of side L=25cm . A fifth
point charge Q=-28 micro coulomb lies a distance z=7cm along the
line perpendicular to the plane of the square and passing through
the center of the square as shown in Figure 3. Calculate the force
exerted by the other four charges on -Q ?
