Coulomb’s law for the magnitude of the force F
between two particles with charges Q
separated by a distance d
, and ϵ
is the permittivity of free space.
Consider two point charges located on the x axis: one charge, q
= -19.0 nC
, is located at x
= -1.745 m
; the second charge, q
= 36.0 nC
, is at the origin (x=0.0000)
What is the net force exerted by these two charges on a third charge q
= 52.5 nC
placed between q
= -1.060 m
Your answer may be positive or negative, depending on the direction of the force.
