An ion moves along a straight line through four sequential parallel conducting grids labeled 1, 2, 3, and 4 in an evacuated chamber where non-electrostatic forces are negligible. The table shows the electric potential \(V\) of each grid, the electric potential energy \(U_E\) of the ion-grid system, and the kinetic energy \(K\) of the ion as it passes through each grid.

Grid	Electric Potential (\(V\))	Electric Potential Energy (\(U_E\))	Kinetic Energy (\(K\))
1	\(+50\text{ V}\)	\(-100\text{ eV}\)	\(150\text{ eV}\)
2	\(+10\text{ V}\)	—	\(K_2\)
3	\(V_3\)	—	\(110\text{ eV}\)
4	\(-20\text{ V}\)	—	\(K_4\)

Which of the following correctly identifies the values of \(K_2\), \(V_3\), and \(K_4\)?
