an atom of helium and one of argon are singly ionized – one electron is removed from each

Here is the answer for the question – an atom of helium and one of argon are singly ionized – one electron is removed from each. You’ll find the correct answer below

an atom of helium and one of argon are singly ionized – one electron is removed from each
the two ions are then accelerated from rest by the electric field between two plate with a potential difference of 150V
what happens after the two ions accelerate from one plate to the other

The Correct Answer is

both have the same KE

Reason Explained

both have the same KE is correct for an atom of helium and one of argon are singly ionized – one electron is removed from each
