"Derive the Bohrâ??s quantisation condition for angular momentum of the orbiting of electron in hydrogen atom, using de Broglieâ??s hypothesis." in

In the Bohr model, the wavelength associated with the electron is given by DeBroglie relationship,

and the standing wave condition that circumference = whole number of wavelengths. In the hydrogenic case, the number n is the principal quantum number.

These can be combined to get an expression for the angular momentum of the electron in orbit. (Note that this assumes a circular orbit, a generally unwarranted assumption.)

 Use in Bohr orbit

Thus L is not only conserved, but constrained to discrete values by the quantum number n. This quantization of angular momentum is a crucial result and can be used in determining the Bohr orbit radii and Bohr energies.

"Find the condition under which the charged particles moving with different speeds in the presence of electric and magnetic field vectors can be used to select charged particles of a particular speed." in

$v=\frac{E}{B}$

Consider a region where a charge q is moving with a speed v. E and B are the Electric and Magnetic fields. v, E and B are perpendicular to each other.

If we want to select a particle of velocity v so it must pass undeflected. This means that electric and magnetic forces acting on it are equal and opposite.

Electrostatic force = qE

Magnetic force =qvB

qE=qvB

=> v = E/B
