A completely ionized beryllium atom (net charge = +4e) is accelerated through a potential difference of 6.0 V. What is the increase in kinetic energy of the atom?

Question

Quizplus · Accepted Answer

The increase in kinetic energy of a charged particle when accelerated through a potential difference V is given by the product of the charge and the potential difference. For a beryllium atom with a charge of +4e, the increase in kinetic energy is 4e * 6.0 V = 24 eV.
