Webb26 nov. 2024 · Inner Surface: σa = qa 4πa2 = − q 4πa2 Outer Surface: σb = qb 4πb2 = Q +q 4πb2 Explanation: Since the electric field must necessarily vanish inside the volume of the conducting sphere, the charges must drift in such a way as to cancel the electric field due to the charge q at the centre. WebbI think so. It'll always produce some heat unless the panels are 100% efficient, which I don't reckon is possible. So either it'll just contain the heat and get hotter and hotter within the sphere until the sphere breaks and the heat is released, or it'll need to radiate the heat over time by glowing in the infrared.
Webb5 apr. 2024 · Hint: Recall that a hollow sphere does not enclose any mass within its boundary. Therefore, the only source of mass which contributes to the moment of inertia of such a sphere is the mass enclosed between the inner and outer radius of the sphere. WebbA hollow sphere, with inner radius a and outer radius b, has a volumetric charge distribution p = kr^2, where r is the distance from the center of the sphere outwards and k is a known constant. Using Gauss's law, find the electric field at r < a, a < r < b, and r > b, and graph the electric field as a function of r. arrow_forward
