Radius of the nucleus is about _______ times less than the radius of the atom.

Q.

The nucleus of an atom can be assumed to be spherical. The radius of the nucleus of mass number A is given by $1.25\times {10}^{-13}\times A^{\frac{1}{3}}$ Radius of atom is one A . If the mass number is 64, then the fraction of the atomic volume that is occupied by the nucleus is

Q. The radius of a hypothetical nucleus (atomic number $=79$) is about $7\times {10}^{-15}$ m. Assuming that charge distribution is uniform, the electric field at distance of $3.5\times {10}^{-15}$ of the nucleus is :

Q. In a hydrogen atom, the electron makes $6.6\times {10}^{15}\text{revolutions per second}$ around the nucleus in an orbit of radius $0.5\times {10}^{-10}\text{m}$. It is equivalent to a current nearly

Q. The radius of an atom is $1^{}$$\times$${10}^{-10}$ m. The radius of the nucleus of this atom is $1^{}$$\times$${10}^{-14}$ m. Calculate how many times that the radius of the nucleus is smaller or greater than the radius of an atom.

Q. A typical atomic nucleus is about $5.0\times {10}^{-15}m$ in radius. Using the uncertainty principle, what should be the lower limit on momentum, that a particle must have if it is to be a part of a nucleus?
