Question

Please show me step by step

An electric field of strength E = 200 N/C is directed along the +x-axis as shown. What is the magnitude of the potential difference between point B and point A if the distance between these two points is 8 cm? V Tries 0/2 An electron is initially at rest at point B. How much kinetic energy (in electron-Volts, or eV) will the electron gain by moving to the higher potential at point A? (Electron-Volt or eV is a unit of energy. An electron traveling across a potential of ONE (or lose) ONE eV. Likewise, if the object has 10 electron charges (-10e), it will gain or lose 10 eV kinetic energy if the potential difference is 1 V.) eV Tries 0/2 What is the kinetic energy of the electron at point A measured in Joules? Tries 0/2

Explanation / Answer

a)

V=Ed =200*0.08

V=16 V

b)

KE=qEd=1.6*10^-19*200*0.08

KE=16 eV

c)

KE=16*1.6*10^-19

KE=2.56*10^-18 J
