Question

An a-particle is accelerated from rest through a potential of V volts. Its final kinetic energy is
(1) 2 eV
(2) 1 eV
(3) 4 eV
(4) 1/2 ev​

Answer 1

Answer:

answer is 2 eV

Explanation:

hope it is helpful

Answer 2

Answer:

as we know , ∆KE = ∆U =q∆V

because charge on an Alpha partical is (+2q)

therefore , KE = 2q×V

hence KE = 2eV

(1) option is correct
