Questions and Exercises The three electrostatic charge configurations in Fig. 5 are in three separated spaces. (1) (3) Figure 5 Three electrostatic charge configurations in three separated spaces 1. Use ruler to draw vector arrows with label Ea, Et, E. on each diagram in Fig. 5 to indicate the electric field lines through points a, b, c respectively in each of the three charge configurations. 2. Let Ea, Ebs E. be the magnitudes of Ea, E;, E. respectively. Use smaller () and equal (=) signs to describe the relationships among Ea, E,, E. in the configurations: configuration (1): configuration (2): configuration (3): . 3. The electric potentials at points a, b, c are denoted Va, Vb and Vc respectively. Use smaller () and equal (=) signs to describe the relationships among Va, Vb and Vc in: configuration (1): ad of Hop configuration (2): configuration (3): 4. Now a negative point charge -q (-q
