Q23 of 37 Page 1

An α - particle and a proton are accelerated through same potential difference. Find the ratio (vα/vp) of velocities acquired by two particles.

Mass of proton = Mp = 1u

Mass of alpha particle = Ma = 4u


Charge on proton = Qp = + 1e


Charge on alpha particle =+ 2e


Now, we should use the formula,



Where P is liner momentum of body


q is charge on body, V is potential difference and m is mass of body.


Then,
