a. an electron because of its smaller mass
b. a proton because of its larger mass
c. an electron because it doesn't feel the nuclear force
d. a proton because it doesn't feel the nuclear force
e. an electron because of its smaller charge
my guess is b
Generally speaking, more massive objects follow the laws of Newtonian mechanics more closely and have less position uncertainty because of their higher momentum, compared to a less massive object with the same velocity. This is a result of the Heisenberg uncertainly principle. Therefore I agree with your answer.
