Consider a 2.00 microCoulomb charge sitting at the point (0.0cm, 0.0cm) , and a -3.00 microCoulomb charge sitting at the point (1.0cm,-1.0cm).

a) determine the electric potential at the point (2.0cm,0.0cm)

b) If a proton travels along a path that passes through the point (2.0cm,0.0cm) and later through the point (4.0cm, 0.0cm) at which point will the proton be moving faster?

c) what would the change in the protons speed be in the previous question?
