The Bohr radius a0 is the most probable distance between the proton and the electron in the Hydrogen atom, when the Hydrogen atom is in the ground state. The value of the Bohr Radius is: 1 a0 = 0.529 angstrom. One angstrom is 10-10 m. What is the magnitude of the electric force between a proton and an electron when they are at a distance of 2.63 Bohr radius away from each other?

The electric force is  

Explanation:

From the question we are told that

    The  Bohr radius at ground state is  

    The values of the distance between the proton and an electron  

The electric force is mathematically represented as

Where n and p are charges on a single electron and on a single proton which is mathematically represented as

    and  k is the coulomb's  constant with a value

substituting values

cell differentiation  is how generic embryonic  cells  become specialized  cells. this occurs  through a process called gene expression. gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a  cell  functions.
