Chapter 25, Problem 44AP
Example 25.1 explored a cylindrical capacitor of length ℓ with radii a and b for the two conductors. In the What If? section of that example, it was claimed that increasing ℓ by 10% is more effective in terms of increasing the capacitance than increasing a by 10% if b > 2.85a. Verify this claim mathematically.
