distance of 17.0 cm .
a.What is the magnitude of the electric field at a point halfway
between the two charges?

Two point charges of +30.0 μC and -9.00 μC are separated by a
distance of 20.0 cm. What is the intensity of the electric field E
midway between these two charges? A. 18.1x106 N / C, towards
positive charge b. 35.1x106 N / C, towards negative charge c. 0 N /
C d. 18.1x106 N / C, towards negative charge

1. A -9.00 nC point charge and a +18.0nC point charge are 15.0
cm apart on the x-axis.
Part A: What is the electric potential at the point on the
xxx-axis where the electric field is zero? Express your answer with
the appropriate units.
Part B: What is the magnitude of the electric field at the point
on the x-axis, between the charges, where the electric
potential is zero? Express your answer with the appropriate
units.

Find the potential at a point 10 cm above the middle of two
point charges of opposite charge, of magnitude Q = 24 μC, 21 cm
apart.
What is the magnitude of the field at that point?

Point charges of -2.93 μC and +6.63 μC are placed 0.898 m apart,
with the negative charge at the origin and the positive charge on
the +y-axis. (a) At what location, in meters, is
the electric field due to these charges zero?

Point charges of -3.59 μC and +5.58 μC are placed 0.6 m apart,
with the negative charge at the origin and the positive charge on
the +y-axis. (a) At what location, in meters, is
the electric field due to these charges zero? Do not enter units
with your answer.
