Unformatted text preview: Chapter 20 Electric Field (Additional Questions) 1-) In the figure given aside, determine the point (other than infinity) at which the electric field is zero. Solution: The point is designated in the sketch. The magnitudes of the electric fields, E 1 , due to the −2.50×10 −6 C charge) and E 2 (due to the 6.00×10 −6 C charge) are Equate the right sides of (1) and (2) The negative value for d is unsatisfactory because that locates a point between the charges where both fields are in the same direction. 2-) In figure, what is the magnitude of the electric field at point P due to the four point charges shown? Solution: We place the origin of our coordinate system at point P and orient our y axis in the direction of the q 4 = - 12 q charge (passing through the q 3 = +3 q charge). The x axis is perpendicular to the y axis, and thus passes through the identical q 1 = q 2 = +5 q charges. The individual magnitudes 1 2 3 E E E + + uur uur uur , and 4 E uur are figured from 2 1 4 q F E q r...
