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?

- wo positively charged protons in a Helium nucleus are separated by about 2 x 10^-15 m. Use Coulomb's law to find the electrical force of repulsion between the two protons. This result will give you an indication of the strength of the STRONG nuclear forcearrow_forwardSuppose a droplet of unknown mass remains suspended against gravity when electric field is -2.70×10^5N/C. What is the minimum mass of the droplet.arrow_forwardIn nuclear fission, a nucleus splits roughly in half. What is the potential 7 ×10-14m from a fragment that has 45 protons in it?arrow_forward
- What 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_forwardAn alpha particle (charge 2e) is aimed directly at a gold nucleus(charge 79e). What minimum initial kinetic energy must the alphaparticle have to approach within 6.0 * 10-14 m of the center of thegold nucleus before reversing direction? Assume that the gold nucleus,which has about 60 times the mass of an alpha particle, remains at rest.arrow_forwardIntegrated ConceptsThe classic Millikan oil drop experiment was the first to obtain an accurate measurement of the charge on an electron. In it, oil drops were suspended against the gravitational force by a vertical electric field. (See Figure 18.58.) Given the oil drop to be 1.00 μm in radius and have a density of 920 kg/m3 : (a) Find the weight of the drop. (b) If the drop has a single excess electron, find the electric field strength needed to balance its weight.arrow_forward

The charge on an argon nucleus is +20earrow_forwardA student said, “During a spark, protons are pulled out ofthe positive ball and jump across to the negative ball.” Give atleast two reasons why this analysis cannot be correct.arrow_forwardCalculate the resultant force on the 2 micro coulomb charge.arrow_forward
- A dust particle acquires a charge of ‐13 nC, how many excess electrons does it carry?arrow_forwardA gold nucleus has a radius of 7.3×10-15 m and a charge of +79e. Through what voltage must an α-particle, with its charge of +2e, be accelerated so that it has just enough energy to reach a distance of 2.5×10−14 m from the surface of a gold nucleus? (Assume the gold nucleus remains stationary and can be treated as a point charge.)arrow_forwardThe liquid-drop model of the atomic nucleus suggests high-energy oscillations of certain nuclei can split the nucleus into two unequal fragments plus a few neutrons. 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
