'Prob.6 An insulating solid sphere of radius R = 6.Ocm has a total positive charge uniformly distributed throughout its volume_ The electric flux through a spherical Gaussian surface of radius r = 3.Ocm is 2.26x 105N.m2/c
Gaussian surface
[a] How much charge (in units of UC) is enclosed by the Gaussian surface of radius r =3.Ocm? (Example: if your answer is 3.4x10-6c =3.4 VC, enter your answer as 3.4 in the answer box).'
