3. Three charges +q, +q and Q are located at the vertices of a right-angled isosceles triangle, Fig. 2. If the total interaction energy is zero what should be the value of Q? +9 +9
4. Figure 3 shows a non-conducting hollow sphere with inner radius b and outer radius a. A total charge Q is uniformly distributed in the material b<r<a. Find the electric field for (a)r <b; (b) b <r<a; (c)r> a.
