Explanation:
For,an electron moving round the nucleus in its orbit,its angular momentum is conserved.
That is,
Now,mass of electron being constant we can say,
Now,kinetic energy of an electron can be written as
So,
so,if kinetic energy is doubled,its velocity will become
So,its radius being inversely proportional to its velocity in an orbit,it will be
