Chapter 42: Q12P (page 1302)
The electric potential energy of a uniform sphere of charge qand radius ris given by (a) Does the energy represents a tendency for the sphere to bind together or blow apart? The nuclide is spherical with radius 6.64fm . For this nuclide, what are (b) the electric potential energy Uaccording to the equation, (c) the electric potential energy per proton, and (d) the electric potential energy per nucleon? The binding energy per nucleon is . (e) Why is the nuclide bound so well when the answers to (c) and (d) are large and positive?
Short Answer
- Yes, the energy represents the tendency for the sphere to bind together.
- The electric potential energy of the nuclide according to the equation is 1.15 GeV .
- The electric potential energy per proton is 12.2 MeV/proton .
- The electric potential energy per nucleon is 4.81 MeV/nucleon .
- The nuclide is bound so well because of the strong force.
