(b) An isolated spherical conductor has charge q, as shown in Fig. 6.1. [Figure 6.1] Point P is a movable point that, at any one time, is a distance x from the centre of the sphere. The variation with distance x of the electric potential V at point P due to the charge on the sphere is shown in Fig. 6.2. [Figure 6.2] Use Fig. 6.2 to determine
