The electric field of each particle is described by the following.
E = ke
Let x represent the distance from the negatively charged particle q_ to the zero-field point to its left. Then
1.00 m + x is the distance from the positive particle of charge q, to this point. At this point, we want to
satisfy the condition
E, + Ẻ_ = 0,
so we have
kela-|
kelal
=
(1 m + x)2
Taking the square root of both sides and cross-multiplying to clear fractions, gives
1/2
1m + x =
1/2
