In a region of space, source charges produce a static electric potential field.

Four identical protons, each having initial kinetic energy \(K_0 = 100\text{ eV}\), travel along different paths between the initial and final electric potentials listed in the table, subject only to conservative electrostatic forces.

Path	Initial Potential \(V_i\)	Final Potential \(V_f\)	Path Length
1	\(+60\text{ V}\)	\(+20\text{ V}\)	\(0.10\text{ m}\)
2	\(+60\text{ V}\)	\(+20\text{ V}\)	\(0.35\text{ m}\)
3	\(+40\text{ V}\)	\(-30\text{ V}\)	\(0.20\text{ m}\)
4	\(+30\text{ V}\)	\(+10\text{ V}\)	\(0.15\text{ m}\)

Which of the following correctly ranks the net change in kinetic energy \(\Delta K\) of the protons along the four paths?
