Textbook Question

Chapter 21, Problem 30MCQ

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 plates with a potential difference of 150 V. After accelerating from one plate to the other,

A. The helium ion has more kinetic energy.

B. The argon ion has more kinetic energy.

C. Both ions have the same kinetic energy.

D. There is not enough information to say which ion has more kinetic energy.
