56. Since the charge distribution is spherically symmetric we may writeE(r)=14πε0qenclr,whereqenclis the charge enclosed in a sphere of radiusrcentered at the origin. Also, Eq. 25-18 isimplemented in the form:V(r)−V(r0Rr0rE(r)dr. The results are as follows: Forr>R2>R1V(rq1+q240randE(rq1+q240r2.ForR2>r>R1V(r140µq1r+q2R2¶andE(rq140r2
