The electric potential outside a charged conducting shpere is 200V, and 10.0 cm farther from the center of the sphere the potential is 150V. Determine
(a) the radius of the sphere and
(b) the charge on it. The electric potential immedeiately outside another charged conductining sphere is 210V, and 10.0 cm farther from the center the magnitude of the eletric field is 400V/m. Determine
(c) the radius of the sphere and
(d) its charge on it.
(e) Are the answers to parts (c) and (d) unique?
