2000E2 (modified) Three particles, A, B, and C, have equal positive charges Q and are held in place at the vertices of an equilateral triangle with sides of length , as shown in the figures below. The dotted lines represent the bisectors for each side. The base of the triangle lies on the x -axis, and the altitude of the triangle lies on the y -axis.  Figure 1  Figure 2 a. i. Point , the intersection of the three bisectors, locates the geometric center of the triangle and is one point where the electric field is zero. On Figure 1 above, draw the electric field vectors , and at P , due to each of the three charges. Be sure your arrows are drawn to reflect the relative magnitude of the fields. ii. Another point where the electric field is zero is point at . On Figure 2 above, draw electric field vectors , and at due to each of the three point charges. Indicate below whether the magnitude of each of these vectors is greater than, less than, or the same as for point .| Greater than at | Less than at | The same as at | |
