Problem
A positively charged particle moves from a location where the electric potential is 200 V to a location where the potential is 50 V. Assuming no non-conservative forces act, which statement best describes the changes in the particle’s electric potential energy (ΔU) and kinetic energy (ΔK) during the motion?
(a) ΔU increases and ΔK decreases by the same amount.
(b) ΔU decreases and ΔK increases by the same amount.
(c) Both ΔU and ΔK increase by the same amount.
(d) ΔU increases while ΔK remains the same.
