An electron and its antiparticle are annihilated after collision. How much energy will be obtained? What will be the wavelength of the emitted radiation (energy)?
(Mass of electron \( =9.1 \times 10^{-31} \mathrm{~kg} \), speed of light \( =3.0 \times 10^{8} \mathrm{~ms}^{-1} \) and Planck's constant \( =6.6 \times \) \( \left.10^{-34} \mathrm{Js}\right) \)
