Question

As sketched in the Ture below, a small-size partide of charge = 7.2 C is situated inside the cavity hollowed out inside a conducting sphere of diameter d=19 cm. For certainty, let us say that the charge is pos toned on the line connecting diametrically coposite points - ANO. P. on the surface of the sphere, restance: 0/4 from point 2. The concting bady Itself is rat charger (statal charges rem). As a result of polarization of this conclucling body, what is the total charge induced on the surface of bile cevily including ils polarity)?: Is this induxr charge distributed in a specially symmetric fashion on the cavity surface: NO What is the total charpe Indicers on the outer for af the sphere?: Is this Induced charge list buted in a spherically-symmetric tesnilon on the outer suitece?: Yes No Find the electric Hledat point on the outer surface: INC How does En compare to the electric field Es at point ?!

Answer 1

Due to change induction , -q charge will be induced on the surface of carity and to change will be indented on the outer surface of sphere. Total change induced on the surface of carity = -7.24C) so This induced chage is such distributed non uni uniformly center of charge lies at the location of point chage q. that center Any No Total charge induced on outer suryace of sphere= [+7.2MC This induced change is distributed on uniforenly outer surface, Ang Yes Electric field at A kq (9x109) (712x10-6) R 19 2X100 682 105.26 N/c 1682.1 KN/C {: There is no effect of inside charges] EA = EB Aust Equal to EB
