A proton and an electron are in a constant electric field (360 V/m) between two oppositely charged plätēs sēparated by of 30.0 cm. A proton is released from rest from the positive plate and the electron is released from rest from the negative plate. We are comparing for kinetic energy gained when they get to the other plate. Which of the following statements is true? V ba electron + proton O A. Both the charges gain the same kinetic energy of 108 ev. O B. Electron gains the larger kinetic energy of 198 kev. C. Proton gains the larger kinetic energy of 198 kev. +

Given:

The electric field is $360 \raisebox{1ex}{$\mathrm{V}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{m}$}\right.$.

The distance between the two plates is 30.0 cm.

Introduction:

Electric field is defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outwards from a positive charge and radially towards a negative point charge.
