Question

Problem 19: There is no electric charge at the point p what can be said about the electric field at point P? (a) The field is zero. (b) The field is positive. (c) The field is negative. (d) Nothing can be said about the field. Problem 20: Consider four separate configura- tions that produce an electric field at a point P in space. Configura- tion 1, a point charge with charge q is a distance d from the point P. Configuration 2, a point charge with charge 2g is a distance d from the point P. Configuration 3, a point charge with charge q is a dis- tance 2d from the point P. Con- figuration 4, a point charge with 40 charge 24 is a distance 2d from the point P. Rank in order, from L largest to smallest, the electric field strengths E to Ei for the four con figurations. Select One of the Following: (b) Eh Es Ea (c) E Ei Es (d) Ei Ei Es (e) E
