a) Points A and B have electric potentials of 255 V and 129 V, respectively. When an electron released from rest at point A arrives at point C its kinetic energy is KEA. When the electron is released from rest at point B, however, its kinetic energy when it reaches point C is KB = 4KEA. What is the electric potential at point C?

b) A charge of 2.87 µC is held fixed at the origin. A second charge of 2.87 µC is released from rest at the position (1.15 m, 0.350 m) . If the mass of the second charge is 3.10 g, what is its speed when it moves infinitely far from the origin?
