Question

The value of 1 GeV in Joules is:

Options

• \[1.6 \times 10^{-10}\ \text{J}\]

• \[1.6 \times 10^{-7}\ \text{J}\]

• \[1.6 \times 10^{-16}\ \text{J}\]

• \[1.6 \times 10^{-13}\ \text{J}\]

Answer 1

1 GeV = 10⁹ eV. Hence \[1\ \text{GeV} = 10^9 \times 1.6 \times 10^{-19}\ \text{J} = 1.6 \times 10^{-10}\ \text{J}\].
