Question

22. If an a-particle and a proton are accelerated from
rest by a potential difference of 1 megavolt then the
ratio of their kinetic energy will be
(1)0.5
(2) 1
(3) 2
(4) 4​

Answer 1

(3)2 just a try I don't know

Answer 2

Answer:

2

Explanation:

2,    I Think because kinetic energy 1/2mv^2= Vq here V=voltage q =charge and charge of alpha particle is twice the proton so it should be 2/1
