Electrons in an x-ray machine are accelerated from rest through a potential difference of 50 000 V.What is the kinetic energy of each of these electrons in eV?
A)50 eV
B)80 eV
C)330 eV
D)50 keV

Question

Quizplus · Accepted Answer

The kinetic energy gained by an electron when accelerated through a potential difference of 50,000 V is 50,000 eV, which is equivalent to 50 keV (since 1 keV = 1,000 eV).
