The nuclear potential energy betweenthe proton and the neutron in a deuteriumnucleus (a hydrogen nucleus with a neutron)has an average value of 2.224 MeV. By howmuch does this interaction change the mass ofthe combined system in MeV/c 2 and kg? Whatis this as a fraction of the combined mass of theproton and the neutron?

The explosive energy of a ton of TNT is 4.184*10° Joules, according to Google. A megaton of TNT is a million times that. According to Wikipedia, the Tsar Bomba e was the most powerful thermonuclear weapon ever exploded, at 50 megatons of TNT. (For comparison, the explosive energy of WWII nuclear bombs was about 20 kilotons.) Suppose one kg of antimatter came into contact with matter. How would the explosive energy compare with the explosive energy of the Tsar Bomba? (c = 3* 10® m/s) O The kg of antimatter would produce at least a hundred times more energy. The Tsar Bomba produced at least a hundred times more energy than the kg of antimatter. O There is no way to compare the two. O They would be approximately the same.
