A) \[2:1:3\]
B) \[1:1:2\]
C) \[1:1:1\]
D) \[1:2:4\]
Correct Answer: B
Solution :
When a particle with charge q passes through a potential difference V, then kinetic energy acquired by particle is \[K=qV\] Given, \[{{q}_{1}}:{{q}_{2}}:{{q}_{3}}=1:1:2\] and \[{{V}_{1}}:{{V}_{2}}:{{V}_{3}}=1:1:1\] \[\therefore \] \[{{K}_{1}}:{{K}_{2}}:{{K}_{3}}=1:1:2\]
