If we take a steel container, fill it completely with water and seal it back (all this at sea-level), and then take it to bottom of sea, what will happen to the container? Will it be crushed? What equation should we use to relate initial and final volume? Kindly help.
A long round dielectric cylinder is polarized so that the vector P = ar, where 'a' is a +ve constant & 'r' is the distance from the axis.find the space density rho` of bound charge as a function of distance r from the axis.
