Question

A point charge q1 (6 nC) is is placed 3 cm away from the origin on the positive x axis and another point charge q2 (-4nc) is placed 3 cm away from the origin on the negative y axis. If an electron is placed at (0, 5). What is the total force acting on the electron?

Please include a picture and a detailed explanation.

Answer #1

A point charge q1=4.20 nC is fixed at the origin. A second point
charge q2=−7.80 nC is fixed at the point x=15.0 cm.
(a) Find the point on the +x axis where the electric potential
is zero.
(b) A third charge, q3=−2.30 nC is then placed at the point
x=20.0 cm. Find the net force acting on charge q2 due to the other
two charges.

A point charge q1 = 3.90 nC is placed at the origin, and a
second point charge q2 = -2.90 nC is placed on the x-axis at x=+
21.0 cm. A third point charge q3 = 2.00 nC is to be placed on the
x-axis between q1 and q2. (Take as zero the potential energy of the
three charges when they are infinitely far apart.)

charges if q3...

A point charge q1 = 3.90 nC is placed at the origin, and a

x-axis between q1 and q2. (Take as zero the potential energy of the
three charges when they are infinitely far apart.)

A point charge q1 = 4.05 nC is placed at the origin,
and a second point charge q2 = -3.05 nC is placed on the
x-axis at x=+ 21.0 cm . A third point charge
q3= 1.90 nC is to be placed on the x-axis between
q1and q2. (Take as zero the potential energy of
the three charges when they are infinitely far apart.)

2. A +2nC charge (q1) is at the origin of the x-axis,
a -4 nC charge (q2) is at (x, y) = (1 cm, 0 cm).
a) The charges divide space into 3 regions: to the left of q1,
between the charges, and to the right of q2. In
which of these 3 regions will a proton, located on the x-axis,
experience forces in opposite directions?
b) At what distance from q1 would the proton experience zero net
force?
