1 MeV is equal to

The correct answer is Option (3) → \( 1.6\times10^{-13}\,\mathrm{J} \)

NCERT (2026-27):
Potential Energy of a Single Charge – “… if an electron with charge q = e = 1.6×10^–19 C is accelerated by a potential difference of ΔV = 1 volt, it would gain energy of qΔV = 1.6 × 10^–19J. This unit of energy is defined as 1 electron volt or 1eV, i.e., 1 eV=1.6 × 10^–19J. The units based on eV are most commonly used in atomic, nuclear and particle physics, (1 keV = 10³eV = 1.6 × 10^–16J, 1 MeV = 10⁶eV = 1.6 × 10^–13J, 1 GeV = 10⁹eV = 1.6 × 10^–10J and 1 TeV = 10¹²eV = 1.6 × 10^–7J).”
