(a) Is the potential difference along any path from A to \(\mathrm{C}\) in Figure \(25.6 c\) positive, negative, or zero? \((b)\) Along any path from \(\mathrm{C}\) to \(\mathrm{B}\) ?

(c) Along the straight path from \(\mathrm{B}\) to A?

(d) In Figure 25.4, is the potential difference between the particle's initial and final positions positive, negative, or zero?

(e) Express this potential difference in terms of the change in the particle's kinetic energy \(\Delta K\) and its charge \(q\).
