Test Prep Electric Fields GP IITopic: Electric Charge Type: Numerical1.How many electrons must be transferred to a body to produce a charge of 125 nC? A)1.25 10–7 D)3.45 1011 B)1.60 10–19 E)7.81 1011 C)1.28 1012 Topic: Conductors and Insulators Type: Conceptual2. If you bring a negatively charged insulator near two uncharged metallic spheres that are in contact and then separate the spheres, the sphere on the right will have Topic: Coulomb's Law Type: Numerical3. Charges q1and q2exert repulsive forces of 15 N on each other. What is the repulsive force when their separation is increased so that their final separation is 160% of their initial separation? Section: 21-3 Topic: Coulomb's Law Type: Numerical4.Point charges of 4.0 10–8C and –2.0 10–8C are placed 12 cm apart. A third point charge of 3.0 10–8C halfway between the first two point charges experiences a force of magnitude 1

Topic: Coulomb's Law Type: Numerical5. If all the charges are 15 cm from the origin (the crossing point of the vertical and horizontal lines) in the above figure and Q= +3.0 C, then calculate the magnitude of the net force on a charge of +Qplaced at the origin. A) 22.8 N B) 10.2 N C) 26.0 N D) 187 N E) None of the above Topic: The Electric Field Type: Numerical6.Q2Q1PTwo charges Q1, and Q2, each equal to 6.4 x 10–19C, are placed like in the picture above, 80 nm from the field point P. The magnitude of the electric and the electricpotential at point P are:
