Question

Consider two point charges located on the x axis: one charge, q1 = -20.0 nC , is located at x1 = -1.650 m ; the second charge, q2 = 33.5 nC , is at the origin (x=0.0000). What is the net force exerted by these two charges on a third charge q3 = 50.0 nC placed between q1 and q2 at x3 = -1.185 m ?

Force on q3 =

Answer 1

if it requires magnitude, we just omit the negative sign.
