1) Jackson 4.9. [20 points] (a)–10 points, (b)–4 points, (c)–6 points.
2) Jackson 4.13 [15 points]
3) Jackson 4.10 [10 points].
4) [15 points] A sphere of radius R is made of a uniaxial dielectric with dielectricconstant ǫ along two principal axes and dielectric constant ǫ3 along the third.The sphere is placed in a uniform electric field, with arbitrary orientation. Findthe torque on the sphere.
