A charge q; = +2 72 JC is at a distance d = 1:73 m from a second charge 92 -4.67 pC. (a) Find the electric potential at a point A between the two charges that is d/4 from q; . Note that the location A In the diagram above is not to scale. X What is the potential due to a point charge at a particular distance from it? Did you consider the sign of each charge when calculating the electric potential? V (b) Find a point between the two charges on the horizontal line where the electric potential is zero. (Enter your answer as measured from q,.) m
