Question

ഒരു ഇലക്ട്രോൺ വോൾട്ട് എന്നതു്.................... ജൂളിന് തുല്യമാണ്.

• A. 1.6 x 10(-¹⁹)
• B. 1.6 x 10¹⁹
• C. 1.6 x 10(-¹³)
• D. 1.6 x 10¹³

Answer 1

Answer:

A. 1.6 x 10(-¹⁹)

An electron volt (eV) is a unit of energy, and it's defined as the energy gained by an electron when it moves through a potential difference of one volt.

To convert electron volts (eV) to joules (J), we use the following conversion factor:

1 eV = 1.602 × 10^(-19) J

This conversion factor is based on the elementary charge of an electron, which is approximately 1.602 × 10^(-19) coulombs.

So, in the given question:

1.6 × 10^(-19) J

is indeed the correct answer, as it's equivalent to approximately 1 electron volt (eV).
