Nucleus of He (α, mass 4m, charge +2e), Nucleus of Hydrogen (H, mass m, charge +e) and Nucleus of deuterium ( d , mass 2 m , charge +e) are exposed in uniform electric field for same time from rest, then choose the correct statement regarding their final speed :-

Options:

Answer:

Solution:

From rest, in the same field for the same time: $v = a t = \frac{qE}{m} t$ . $\frac{q}{m}$ : $α = \frac{2 e}{4 m} = \frac{e}{2 m}$ , $d = \frac{e}{2 m}$ , $H = \frac{e}{m}$ .

So $v_{α} = v_{d} < v_{H}$ . Option (C).
