PHYS208 Fundamentals of Physics II
Hint for Ch. 27, 41P
a. Divide the "truncated right-circular cone" into a series of cylindrical disks of
infinitesimal thickness dx and radii that vary accordingly
from a to b. Span the series of disks by integrating over the location variable
The solution in CD-Physics 2.0 puts the assumption above (infinitesimal disks in series)
on firmer ground.
b. Let a = b.
