What is the net force exerted by these two charges on a third charge q 3 = 45.0nC placed between q 1 and q 2 at x 3 = -1.145m ?

Your answer may be positive or negative, depending on the direction of the force.

Coulomb's law for the magnitude of the force F between two particles with charges Q and Q �Œ separated by a distance d is

|F|=K|QQ �Œ | d 2 ,

where K=1 4ƒÎϵ 0 , and ϵ 0 =8.854�~10 −12 C 2 /(N⋅m 2 ) is the permittivity of free space.

Consider two point charges located on the x axis: one charge, q 1 = -14.5nC , is located at x 1 = -1.715m ; the second charge, q 2 = 32.5nC , is at the origin (x=0.0000) .
