An electron with an initial speed of 5.05x10^5 m/s is brought to rest by an electric field. The charge of an electron is -1.60x10^-19C and its mass is 9.11x 10^-31 kg.

a) did the electron move into a region of higher electric potential or lower electric potential? Explain

b) What was the electric potential difference that stopped the electron?

Expert Solution

Electric potential difference that stopped the electron can be find by following formula

Kinetic energy=Potential energy

Electric potential difference that stopped the electron,V=0.726 V
