JEE PHYSICS MCQ: ATOMS

In separate experiments, four different particles each start from far away with the same speed and impinge directly on a gold nucleus. The masses and charges of the particles are

particle 1: mass ${m}_0$, charge ${q}_0$

particle 2: mass $2{~m}_0$, charge $2{q}_0$

particle 3: mass $2{~m}_0$, charge ${q}_0 / 2$

particle 4: mass ${m}_0 / 2$, charge $2{q}_0$

Rank the particles according to the distance of closest approach to the gold nucleus, from smallest to largest.
