Rashid (sar3553) gauss" law ch22 storr (37537) Multiple-choice questions may continue on the next column or page nd all choices before answering. Consider a solid insulating sphere of radius with nonuniform charge density = a r, where a is a constant. b dr r. Q = z dq = 4 az r. If a = 7 10 6 c/m4 and b = 1 m, nd e at r = 0. 6 m. the permittivity of a vacuum is. Find the charge qr contained within the radius r, when r < b as in the gure. The volume element dv for a spherical shell of radius r and thickness dr is equal to 4 r2 dr. Let : a = 7 10 6 c/m4 , r = 0. 6 m , 0 = 8. 85419 10 12 c2/n m2 . and: qr , qr = a r4 r3.
