dV H=- dR = — 7 ^2 when R >a.= 0 when R < a. Therefore the shell attractsa particle which is outsidewith the same force as ifall of its mass were concen-trated at its center. On theother hand the shell exertsno force on a particle whichis within the shell. The dis-tribution of V and H in… … FIELDS OF FORCE AND NEWTONIAN POTENTIAL 215 There are two cases-which have to be considered separately. (a) Point Outside the Sphere. — Consider the sphere to be madeof concentric shells of thickness dp. Then, since the point is outside everyone of these shells the potential due to any one of the…
