If a particular protein contains 178 amino acids, and there are 367 nucleotides that make up the introns in this gene. $$, $$ The text also provides foundational material for the emerging field of nanotechnology. We used Gauss' Law to show that the field inside the shell was zero, and outside the shell the electric field was the same as the field from a point charge with a charge equal to the charge on the shell and placed at the center of the shell. Express your answer in terms of variables Q. L. r, and R. Combine all numerical values together into one multiplier. However, a simpler way to think about this problem is to use a single variable, x, to denote the distance to a specific ring making up the cylinder. To evaluate the electric field outside the spherical shell, we take point P outside the shell at a distance r from the centre of the spherical shell.
