2. A +2nC charge (q1) is at the origin of the x-axis, a -4 nC charge (q2) is at (x, y) = (1 cm, 0 cm).
a) The charges divide space into 3 regions: to the left of q1, between the charges, and to the right of q2. In
which of these 3 regions will a proton, located on the x-axis, experience forces in opposite directions?
b) At what distance from q1 would the proton experience zero net force?
c) At what distance from q1 would an electron experience zero net force?
