What is the energy equivalent of 2 e V?

To find the energy equivalent of 2 eV, we need to use the conversion factor between electronvolts (eV) and joules (J).

1 eV is equivalent to 1.602 x 10^-19 J.

So, to convert 2 eV to J, we multiply it by the conversion factor:

2 eV * (1.602 x 10^-19 J/eV) = 3.204 x 10^-19 J

Therefore, the energy equivalent of 2 eV is approximately 3.204 x 10^-19 J.
