Q1. Points A and B have electric potentials of 293 V and 149 V, respectively. When an electron released from rest at point A arrives at point C its kinetic energy is KA. When the electron is released from rest at point B, yet, its kinetic energy while it reaches point C is KB = 4KA.
Q2. A ship sets out to sail to a point 148 km due north. An unexpected storm blows the ship to a point 148 km due east of its starting point. (a) How far (in km) and (b) in what direction (as an angle from due east, where north of east is a positive angle) should it now sail to reach its original destination?
