an electron is accelerated from rest through a potential difference 12 V. What is the change in electric potential energy of the electron?

In a 15-volt potential, a particle has a potential energy of -0.45 J. What is the particle's charge?

Cathode-ray tubes (CRTS) are often found in oscilloscopes and computer monitors. In the figure (Eigure 1)an electron with an initial speed of 6.80x108 m/s is projected along the axis midway between the deflection plates of a cathode-ray tube. The potential difference between the two plates is 26.0 V and the lower plate is the one at higher potential.
