If a doubly-ionized oxygen atom (O^-2)is accelerated from rest by going through a potential difference of 32 V,what will be the change in its kinetic energy? A)16 eV B)32 eV C)64 eV D)51 eV E)none of the above

Question

Quizplus · Accepted Answer

The change in kinetic energy of a charged particle is equal to the charge of the particle multiplied by the potential difference. A doubly-ionized oxygen atom has a charge of -2e, so the change in kinetic energy is 2e * 32 V = 64 eV.
