The pressure at 10 {\rm m} below the surface of the ocean is about2.00×105Pa. Which of the following statements istrue?The weight of a column of seawater 1{\rm m}^2 in cross section and 10 {\rm m} high is about 2.00×105\rm N. The weight of a column of seawater 1{\rm m}^2 in cross section and 10 {\rm m} high plus the weight of a column of air with thesame cross section extending up to the top of the atmosphere isabout 2.00×105\rm N. The weight of 1 {\rm m}^3 of seawater at 10 {\rm m} below the surface of the ocean is about2.00×105\rm N. The density of seawater is about2.00×105 times the density of air at sealevel.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
