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.
Express your answer numerically in newtons to three significant figures.
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) .
