Suppose the particle is placed at the 40V equipotential surface along the line connecting the two central positive and negative charges. (hint: The electric field can be obtained using the 40V and 30V potential difference lines.) 65 m = r What is the force on the charged particle if q=80μC? (mN) (m-milli 10-3)
