Answer: 947. 875GeV
Explanation:
According to einstein's E = mC^2
Energy can be converted to mass and mass can be converted to energy. The 'c' in the formula is the speed of light.
When two atomic particle of opposite charges collide they anhilate each other completely to release energy.
The energy released is the sum of the energy they possessed and the energy due to their mass being converted into energy.
Since each particle has an energy of 473 GeV each, then the total sum of the energy they posses is 473*2= 946 GeV
According to experiment, a proton and an anti proton have the same mass, and this has been shown to be equal 1.007276u.
Basic conversion has it that;
1u = one-twelfth the mass of one atom of the carbon-12 isotope.
This means;
1u = 1.66*10^-27 kg = 391 Mev = 0.391GeV,
According to energy mass conversion.
Total mass of the colliding particles = 1.007276 * 2 = 2.014552u
Therefore energy of colliding particles due to mass conversion
= 2.014552 * 0.931GeV
= 1.875 GeV
Total energy liberated in this process equal
946 + 1.875 = 947.875 GeV
