1. From your reading about electric fields, you know that the direction of an electric field is defined as the direction a small positive charge (test charge) would move when placed in the field. With this in mind, respond to the following. 1 a. State what will happen when a positive particle has an initial velocity opposite to the direction of the electric field b. State what will happen when a positive particle has an initial velocity in the same direction as the electric field (2 2. Use Newton's second law to explain the motion you described in question 1. 2 3. Describe the motion of a positive particle when the direction of its initial velocity is perpendicular to the direction of the electric field. 18 Physics 30
