Check whether the gravitational force between two protons in nucleus is balanced by their electrical repulsion, calculate the ratio of this electrical force to the gravitational force and determine whether this ratio has any dependence on the distance between the protons.
Answer to Problem 58E
No. The value of
Explanation of Solution
The gravitational force between two protons in a nucleus is too weak in comparison with the electoral repulsive force between them. In femtometer
Write the formula to calculate the magnitude of Columb electrical force between two protons.
Here,
Write the formula to calculate the magnitude of gravitational force between two protons.
Here,
Divide equation (1) by equation (2).
Substitute
The above ratio shows that
Conclusion: Therefore, force of gravity between protons is not balanced by their electrical repulsive force, the value of

- The atomic weight of cadmium is 112.41, and its density is 8.65 g/cm3. Using Figure 14.3, estimate the attenuation distance of a thermal neutron beam in cadmium. (The attenuation distance is the distance traveled after which the intensity of the beam is reduced to 1/e of its initial value, where e is the base of the natural logarithms.)arrow_forwardSilver has two stable isotopes. The nucleus, 47107Ag , has atomic mass 106.905095 g/mol with an abundance of 51.83% ; whereas 47107Aghas atomic mass 108.904754 g/mol with an abundance of 48.17% . Find the atomic mass of the element silver.arrow_forward(a) Show that if you assume the average nucleus is spherical with a radius r=r0A1/3, and with a mass at A u, then its density is independent at A. (b) Calculate that density in u/fm3 and kg/m3, and compare your results with those found in Example 31.1 for 56Fe.arrow_forward
