Option 1: The kinetic energy of both the particles will be different.

This statement is correct. The kinetic energy of a particle is directly proportional to its mass and the square of its velocity. Since the electron and the proton have different masses, their kinetic energies will be different.

Option 2: The speed of the electron will be higher than that of the proton.

This statement is correct. The speed of a particle is determined by its charge and the potential difference it is subjected to. Since the electron has a smaller mass and the same charge as the proton, it will experience a greater acceleration and reach a higher speed compared to the proton.

Option 3: The speed of the proton will be higher than that of the electron.

This statement is incorrect. As mentioned earlier, the electron will have a higher speed than the proton due to its smaller mass and the same charge.

Option 4: The speed of the electron and the proton will be equal.

This statement is incorrect. The speeds of the electron and the proton will not be equal since they have different masses and experience the same potential difference. The electron, being lighter, will have a higher speed than the proton.

In conclusion, option 2 is the correct statement. The speed of the electron will be higher than
