Acharged paint is spread in a very thin uniform layer over the surface of a plastic sphere of diameter 18.0 cm , giving it a charge of-29.0 μc .
a find the electric field just inside the paint layer.
express your answer with the appropriate units. enter positive value if the field is directed radially inward and negative value if the field is directed radially outward.
b find the electric field just outside the paint layer.
express your answer with the appropriate units. enter positive value if the field is directed radially inward and negative value if the field is directed radially outward
c find the electric field 6.00
cm outside the surface of the paint layer.
express your answer with the appropriate units. enter positive value if the field is directed radially inward and negative value if the field is directed radially outward.

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?
