Part B Calculate the speed of an electron after it accelerates from rest through a potential difference of 330V .

Explanation / Answer

v = sqrt ( 2 qV / m)

A)

v = sqrt ( 2 * 1.6 * 10^-19 * 330 / ( 1.67*10^-27) )

= 2.514 * 10^5 m/s

B)

v = sqrt ( 2 * 1.6 * 10^-19 * 330 / ( 9.1*10^-31) )

= 1.077 * 10^7 m/s
