Immediately outside a conducting sphere of unknown charge Q and radius R the electric potential is 180 V, and 10.0 cm further from the sphere, the potential is 120 V. (a) Determine the radius R of the sphere (in cm). cm (b) Determine the charge Q on the sphere (in nC). nC (c) The electric potential immediately outside another charged conducting sphere is 200 V, and 10.0 cm farther from the center the magnitude of the electric field is 450 V/m. Determine the radius (in cm) of any sphere for which this is possible. (Enter your answers from smallest to largest. If only one value exists, enter "NONE" in the second answer blank.) R, = cm R2 cm (d) Determine the charge on the sphere (in nC) for each value of R. (If only one value exists, enter "NONE" in the second answer blank.) nC 91 92 nC
