Question

The value of 1 MeV in Joules is:

Options

• \[1.6 \times 10^{-13}\ \text{J}\]

• \[1.6 \times 10^{-16}\ \text{J}\]

• \[1.6 \times 10^{-10}\ \text{J}\]

• \[1.6 \times 10^{-7}\ \text{J}\]

Answer 1

1 MeV = 10⁶ eV. Multiplying, \[1\ \text{MeV} = 10^6 \times 1.6 \times 10^{-19}\ \text{J} = 1.6 \times 10^{-13}\ \text{J}\].
