particle and the point in space at which the
electric field is being calculated. c) The
separation of the two charged particles. d) None
of the above.

Three charged particles lie on the x axis one at
the origin, one to the left of the origin (that
is, at a position having a negative x value), and
another to the left of that one. A person is
asked to determine the electric field due to the
trio, at a point on the positive y axis. The
person determines the distance r that each
particle is from the point on the y axis in
question and then calculates the value of
for each of the three particles in turn.
Then the person adds the three values thus
determined and gives the sum as the total
electric field at the point on the y axis in
question. Is this procedure correct?
a) Yes. b) No.

In calculating the electric field due to a
charged line segment, one considers each bit of
the line segment to be a point charge.
a) True. b) False.
