to start a nuclear fusion reaction, two hydrogen atoms of charge 1.602x10^19 and mass 1.67x10^27kg must be fired at each other. If each particle has an initial velocity of 2.7x10^6m/s when released, what is their minimum seperation?

KE =PE
mv²/2= ke²/r ,
r= 2•k•e²/m•v²,
where
k =9•10^9 N•m²/C²,
e =1.6•10^19 C,
m =1.66•10^27 kg.
