PhysicsEasysingle choice

If an alpha particle and a proton are accelerated from rest by a potential difference of $1 MeV$ , then the ratio of their kinetic energies will be

Options:

Answer:

Solution:

From conservation of mechanical energy

$Δ K E = q (V_{i} - V_{f})$

$\frac{K_{α}}{K_{p}} = \frac{2 e (V)}{e (V)}$

$\frac{K_{α}}{K_{p}} = \frac{2}{1}$
