For a charged hollow metal sphere with total charge Q and radius R centered on the origin:
Select "True"or "False" for each statement.The field in the hollow of the shell is not zero.There is zero net charge on the outside surface.The fieldfor r >> R will be thesame as the field of a point charge, Q, at the origin.The electric field is zero just inside the metal.The E-field near the outside surface is normal tothe surface.The total charge is on the outside surface.
Two children setup a "telephone" by placing a long, slender aluminium (Y = 6.9 × 1010 N/m2) bar that has a length of 6.1-m between their two houses. To communicate, the child taps a coded message on one end. How long do the sound waves take to reach ..
