... the particles are sufficiently far apart so that the only force acting on each particle after it is released is that due to the electric field. At a later time when the particles are still in the field, the electron and the proton will have the same (A) direction of motion (B) speed (C) displacement ...

... If you ask a random collection of first year students, “What do you know about relativity?” the answers might be: “All is relative?” “It all depends on your frame of reference.” “You will never measure an absolute velocity unless you look into space.” “Wasn’t it invented by the same guy that gave us ...
