A charged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 12.0 cm, giving it a charge of -35 u.
(a) Find the electric field at the surface of the sphere just outside the paint layer.
(b) Find the electric field at 5.00 cm outside the surface of the paint layer.
Select one:
E = 6.50 x 107 N/C, E = 2.60 x 107N/C
E = 1.50 x 107 N/C, E = 1.20 x 10°N/C
E = 0.03 x 10' N/C, E = 0.23 x 10°N/C
None of these is correct
E = 8.74 x 107N/C, E = 5.40 x 10' N/C
E = 8.74 x 10' N/C, E = 2.60 x 10' N/C
E = 6.50 x 10N/C, E = 5.40 x 10?N/C
