Coulomb's law for the magnitude of the force F between two particles with charges Q and Q′ separated by a distance d is
|F|=K |QQ'|/d2
where K=1/4πϵ0 , and ϵ0=8.854×10-12 C2/(N⋅m2) is the permittivity of free space.
Consider two point charges located on the x axis: one charge, q1 = -17.0 nCn, is located at X1 = -1.680 m ; the second charge, q2 = 30.0 nC , is at the origin (x = 0).
What is (Fnet3)x, the x-component of the net force exerted by these two charges on a third charge q3= 53.0 nC placed between q1 and q2 at X3 = -1.165 mm ?
Your answer may be positive or negative, depending on the direction of the force.
