The kinetic energy of the electron after the head collision with the photon will be 9.93 x 10⁻¹⁶ J.
Kinetic energy of the electron
The kinetic energy of the electron is calculated as follows;
K.E = qV
where;
- q is charge of electron
- V is potential energy of the electron
- 1 eV = 1.602 x 10⁻¹⁹ J
K.E = 6.2 x (10³) x 1.602 x 10⁻¹⁹ J
K.E = 9.93 x 10⁻¹⁶ J
Thus, based on the principle of conservation of energy, the kinetic energy of the electron after the head collision with the photon will be 9.93 x 10⁻¹⁶ J.
