Question

Two spherical cavities, of radii a and b, are hollowed out from the interior of a (neutral) conducting sphere of radius R (see attatched image). At the center of each cavity a point charge is placed. Call these charges qa and qb.

Find the surface charge densities σa, σb, and σR.

The image depicts a diagram illustrating the interaction between two charges, \( q_a \) and \( q_b \). Each charge is located at the center of a circle, representing its position in space. - The charge \( q_a \) is accompanied by a vector labeled \( \mathbf{a} \), indicating the direction and possibly the magnitude related to a force or field associated with \( q_a \). - Similarly, the charge \( q_b \) is accompanied by a vector labeled \( \mathbf{b} \). - The vector \( \mathbf{R} \) connects the two charges, pointing from \( q_a \) towards \( q_b \). This vector represents the distance and direction between the two charges, which is crucial for computing the interaction forces or fields between them according to Coulomb’s Law or electric field principles. The overall grey circle could potentially represent a boundary or region of influence surrounding the charges. This diagram is often used to illustrate principles of electrostatics, such as the forces between point charges and vector relationships in a field.
