Suppose the magnitude of Nuclear force between two protons varies with the distance between them as shown in figure. Estimate the ratio Nuclear force/Coulomb force for a. x=8 fm b. x=4 fm, c. x=2 fm and d. x=1 fm (1fm`=10^-15m)`.

Find the electric force between two protons separted by a distance of 1 fermi (1fermi = 10^(15)m). The protons in a nucleus remain at a separaton of this order.

If the distance between two points (x, 7) and (1, 15) is 10, find the value of x

Two protons are kept at a separation of 10 nm . Let F_n and F_e be the nuclear force and the electromagnetic force between them.

The repulsive force between two like charges of 1 coulomb each separated by a distance of 1 m in vacuum is equal to

Let F_pp, F_pn and F_nn denote the magnitudes of the nuclear force by a proton on a proton, by a proton on a neutron and by a neutron on a neutron respectively. When the separation is 1 fm ,

Suppose ana attractive nuclear force acts between two protons which may be written as F = Ce^(-kr) //r^2, (a) Write down the dimensional formulae and appporpriate SI units of C and k. (b) Suppose that k = 1 fermi^(-1) and that the repulsive electreic force between the protons is just blanced by the attractive nuclear force when the separation is 5 fermi. Find the value of c.
