What is kinetic energy?
A particle or item in motion has a form of energy called kinetic energy. When work, which entails the energy transfer is done on an object by applying a net force, that object acquires kinetic energy.
In the electric field, the electron loses potential energy while gaining kinetic energy. You may calculate the kinetic energy as
[tex]K=\frac{m_e v^2}{2}=e E d[/tex]
Here,
[tex]\text { } m_e=9.11 \cdot 10^{-31} \mathrm{~kg}[/tex] is the mass of the electron;
[tex]e=1.6 \cdot 10^{-19} C[/tex] is the charge of the electron;
E is the electric field;
The distance that an electron travels is called d;
When we solve for the electron's speed, we arrive at:
[tex]v=\sqrt{\frac{2 e E d}{m_e}}[/tex]
Calculate yields:
[tex]v=\sqrt{\frac{2 \cdot 1.6 \cdot 10^{-19} C \cdot 0.060 N / C \cdot 3.6 \cdot 10^{-8} \mathrm{~m}}{9.11 \cdot 10^{-31} \mathrm{~kg}}} \approx 27,5 \mathrm{~m} / \mathrm{s}[/tex]
