Circle the best answer to each Question. Other marks say be made on the exam but wily the answer will be graded. 1. When two charges q1 and q2 are placed 20cm apart there is a force of 16N between them. what would the force between them be if instead they were placed 40cm apart? a. 2N b. 4N c. 8N d. 32N e. 64N f. 128N 2. Charge A is attracted to charge B. Charge B is attracted charge C. Therefore, charge C________ charge A. a. Attracts b. repels c. produces zero force on d. not enough information is given to answer this. 3. What is the general direction of the electric field due to charges Q1

Charge A is attracted to charge B. Charge B is attracted charge C. Therefore, charge C________ charge A. a. Attracts b. repels c. produces zero force on d. not enough information is given to answer this. 3. What is the general direction of the electric field due to charges Q1 and Q2 at point P? a. Northeast b. Northwest c. Southeast d. Southwest e. Electric field has no direction. FOR THE NEXT TWO QUESTIONS: Consider the electric field map showing a uniform electric field of 30N/C pointing to the right. A charge Q = -SC moves with velocity v-4m/s at an angle of 30 degree to the electric field. 4. At which point is the lowest voltage? a. A b. B c. C d. D e. all same voltage 5. What are the magnitude and direction of the electric force on the charge Q? (a) MAGNITUDE: A. 150N b. 300N c. 520N d. 600N e. ON (b) DIRECTION: indicate the direction of the force by drawing an arrow.
