The electric potential immediately outside a charged conducting sphere is $$200 \,V$$, and 10.0 cm fartherfrom the center of the sphere the potential is 150 V.Determine
(a) the radius of the sphere and
(b) the charge on it. The electric potential immediately outside another charged conducting sphere is 210 V, and10.0 cm farther from the center the magnitude of the electric field is 400 V/m. Determine
(c) the radius oft he sphere and (d) its charge on it.
(e) Are the answers to parts (c) and (d) unique?
