Question

Which of the following are true about nuclear force

The nuclear force acts between a neutron and an electron.
The nuclear force strength varies as 1/R, where R is the distancefrom the nucleon.
The nuclear force is essentially zero at distances more than a fewfm.
There are two types of nuclear forces, the strong nuclear force andthe weak nuclear force.
In stable nuclei, the nuclear force is stronger than the coulombicforce.
The nuclear force acts between a proton and an electron.
The nuclear force strength varies as R^-2, the same as thegravitational and the electrical forces.
The nuclear force acts between two protons, between two neutrons,and between a proton and a neutron.
