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
