Calculate the velocity of an electron in Bhor's first orbit of hydrogen atom. (Given r=0.53 xx 10^(-10)m )

The mass m of an electron is 9.1 xx 10^(31)kg and the velocity v of an electron in the first Bohr orbit of a hydrogen atom is 2.2 xx 10^(6)ms^(-1) . Assuming that the velocity is known within 10% (Deltav = 0.22 xx 10^(6)ms^(-1)) , calculate the uncertainty in the electron's position in a hydrogen atom. Strategy: According to Heisenberg's principle, the uncertainty in the postion (Deltax) of any moving particle multiplied by the uncertainity of momentum (Deltap_(x)) can never be less than h//4pi . In the given case, Delta v is known and we need to find Deltax .
