SUMMARY
A force is considered radially symmetric if it depends solely on the radial distance "r" and has only a radial component in the direction of "er". This means that the force remains constant at any point on a circle of radius "r". The discussion clarifies that a field is radially symmetric if it maps onto itself under rotations, indicating that the expression for the force remains unchanged regardless of the orientation of the coordinate axes. An example provided is the magnetic field around a current-carrying wire, which exhibits radial symmetry despite not pointing radially.
