Using Bohr's postulates of the atomic model, derive the expression for radius of n-th electron orbit. Hence obtain the expression for Bohr's radius.

Using Bohr's porstulates of atomic model, derive the expression for the radius of the n^(th) orbit.

State two postulates of Bohr atom model

Derive the equation for radius of n th shell form Bohr theory.

Using Bohr's postulates, derive the expression for the frequency of radiation emitted when electron in hydrogen atom undrgoes transition from higher energy state (quantum number n_i ) to the lower state ( n_f ). When electron in hydrogen atom jumps from energy state n_i=4 to n_f=3,2,1 , identify the spectral series to which the emission lines belong.

In a series LCR circuit connected to an ac source of voltage v=v_msinomegat , use phasor diagram to derive an expression for the current in the circuit. Hence obtain the expression for the power dissipated in the circuit.Show that power dissipated at resonance is maximum.

Derive the expression of 1st Bohr orbit applying Bohr’s 'theory.

Using Rutherford model of atom , derive the expression for the total energy of the electron in hydrogen atom. What is the significance of total negative energy possessed by the electron ?
