Question

Problem 19: There is no electric charge the point P. What can be said about the electric field at point P? Select one of the following (a) The field is zero. (b) The field is positive (c) The field is native. (d) Nothing can be said about the field. Problem 20: Consider four separate configurations that produce an electric field at a point P in space. Configuration 1, a point charge with charge q is a distance d from the point P. Configuration 2, a point charge with charge 2q is a distance d from the point P. Configuration 3, a point charge with charge q is a distance 2d from the point P. Configuration 4, a point charge with charge 2q is a distance 2d from the point P. Rank in order, from largest to smallest , the electric field strengths E1 to E4 for the four configurations Select One of the Following: (a) E2 > E4 > E1 > E3 (b) E2> E1 > E3> E4 (c) E2> E1 = E4 > E3 (d) E2> E1 > E4> E3 (e) E1 = E4 > E2 = E3
