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 x.

The solution in CD-Physics 2.0 puts the assumption above (infinitesimal disks in series) on firmer ground.

b. Let a = b.
