if electron are caused to fall through a potential difference of 100000 voltage , determine their final speed if they were initially at rest.

Kinetic Energy = e*V = (1/2)_mv^2
v = sqrt[2eV/m]
V = 100,000 volts (capital V)
e and m are the electron charge and mass in SI units.
Solve for velocity v (lower case)
