1. A + 0.2 μC charge is in an electric field. What happens if that charge is replaced by a + 0.4 μC charge?
(a) The electric potential doubles, but the electric potential energy stays the same.
(b) The electric potential stays the same, but the electric potential energy doubles.
(c) Both the electric potential and electric potential energy double.
(d) Both the electric potential and electric potential energy stay the same.
2. Two identical positive charges are placed near each other. At the point halfway between the two charges,
(a) The electric field is zero and the potential is positive.
(b) The electric field is zero and the potential is zero.
(c) The electric field is not zero and the potential is positive.
(d) The electric field is not zero and the potential is zero.
(e) None of these statements is true.
