Fusion probability is greatly enhanced when appropriate nuclei are brought close together, but mutual Coulomb repulsion must be overcome. This can be done using the kinetic energy of high-temperature gas ions or by accelerating the nuclei toward one another. (a) Calculate the potential energy of two singly charged nuclei separated by 1 .00 × 10-12 m by finding the voltage of one at that distance and multiplying by the charge of the other. (b) At what temperature will atoms of a gas have an average kinetic energy equal to this needed electrical potential energy?

- Four electrons are located at the corners of a square 10.0 nmnm on a side, with an alpha particle at its midpoint. How much work is done by the Coulomb force when the alpha particle moves to the midpoint of one of the sides of the square? Express your answer in joules.arrow_forwardHow much work is required to bring three protons, initially infinitely far apart, to a configuration where each proton is 1.68E-15 m from the other two. (This is a typical separation for protons in a nucleus.)arrow_forwardProtons enter a region of electric field where the potential difference between where the protons enter and exit is +5×106 volts (5 MV). Assuming the initial energy of the protons was negligible, how much energy does the proton gain? What if we had a fully ionized carbon-12 nucleus instead?arrow_forward

What is Q?(b) What is the electric potential at a distance of 2.5x10-15 m away from a proton?(c) What is the electric potential energy of a system that consists of two protons 2.5x10-15 m apart, as might occur inside a typical nucleus?arrow_forward(II) (a) What is the electric potential 2.5 x 10-15 maway from a proton(charge +e) (b) What is the electric potential energy of a system that consists of two protons 2.5 x10-15 m apart—as might occur inside a typical nucleus?arrow_forwardThe protons in a nucleus are approximately 2 ✕ 10−15 m apart. Consider the case where the protons are a distance d = 1.85 ✕ 10−15 m apart. Calculate the magnitude of the electric force (in N) between two protons at this distance.arrow_forward
- Two positive nuclei each having a charge q approach each other and electrons concentrate between the nuclei to create a bond. Assume that the electrons can be represented by a single point charge at the mid-point between the nuclei. Calculate the magnitude this charge must have to ensure that the potential energy is negative.arrow_forwardA typical carbon nucleus contains 6 neutrons and 6 protons. The 6 protons are all positively charged and in very close proximity, with separations on the order of 10-15 meters, which should result in an enormous repulsive force. What prevents the nucleus from dismantling itself due to the repulsion of the electric force? a. The attractive nature of the strong nuclear force overpowers the electric force. b. The weak nuclear force barely offsets the electric force. c. Magnetic forces generated by the orbiting electrons create a stable minimum in which the nuclear charged particles reside. d. The attractive electric force of the surrounding electrons is equal in all directions and cancels out, leaving no net electric force.arrow_forwardWhat is the magnitude of the repulsive electrostatic force between two protons in a nucleus? Consider the distance between the centers of the protons to be 3.5 x 10^-13 m.If these protons were released from rest, Calculate the magnitude of their initial acceleration?arrow_forward

The fission products acquire kinetic energy from their mutual Coulomb repulsion. Assume the charge is distributed uniformly throughout the volume of each spherical fragment and. immediately before separating each fragment is at rest and their surfaces are in contact. The electrons surrounding the nucleus can be ignored. Calculate the electric potential energy (in electron volts) of two spherical fragments from a uranium nucleus having the following charges and radii: 38e and 5.50 10-15 m. and 54e and 6.20 10-15 m.arrow_forward
