A charge
Q=3.15\times 10^(-4)C
is distributed evenly along a rod of length
L=19cm
, extending from
y=-(L)/(2)
to
y=+(L)/(2)
, as shown in the diagram below. A charge
q=2.9\times 10^(-6)C
, and the same sign as
Q
, is placed as so on the picture, where
D=67cm
, and represents the length along the x-axis from the rod to the charge. Please use integration to compute the total force on
q
in the
x
direction.
