Correct answer: D. If both assertion and reason are false.

As q E=(m v^2)/(r), r=(m v^2)/(q E)=(2 K)/(q E) (. where .K=(1)/(2) m v^2) i.e., r (1)/(q) . Since electron and proton have equal charge, r is the same for both of them. Here, r depends on K (which is given to be the same for both the particles) and as such not on their masses.
