|
1.14 x 10-30 kg
|
|
|
9 x 1016 kg
|
|
|
1.8 x 1012 kg
|

Explanation:
Detailed explanation-1: -Answer: 0.114444 g amount of mass need to convert into energy to get that energy. Explanation: From question we have E=1.03×1013 J E = 1.03 × 10 13 J .
Detailed explanation-2: -Gamma rays ( ) are electromagnetic waves, rather like X rays and radio waves. Thus gamma rays have no mass and no charge.
Detailed explanation-3: -Gamma rays, a form of nuclear and cosmic EM radiation, can have the highest frequencies and, hence, the highest photon energies in the EM spectrum. For example, a -ray photon with f = 1021 Hz has an energy E = hf = 6.63 × 10−13 J = 4.14 MeV.
Detailed explanation-4: -An electron positron pair is produced by a gamma ray photon of energy 2.26 MeV.
