HA 5.3 Spheres connected by a thin wire. [20 points] Consider a conducting hollow sphere, A, with internal radius R, and external radius R2. Con- sider then a second sphere, B, also conducting (but full this time), with radius Rs. The two spheres are assumed to be very far from each other and connected by a conducting wire with negligible cross-section. A third conducting sphere, D, with radius Ro
