Question

the volume charge density of a solid non-conducting sphere of radius R=5.60cm vries with radial distance r as given by distance =(14.1 pc/m.m.m)r/R (a)what is the sphere,s total charge?what is the field magnitude E at(b)r=0,(c)r=R/2.00 and (d)=R?(e) graph E versus r.
​

Answer 1

Answer:

The volume charge density of a solid nonconducting sphere of radius R = 5.60 cm varies with radial distance r as given by p=(35.4pC/m3)r/R.
