Default Re: M.Tech (Nano Technology) Entrance Exam Model Question paper

As you need the M.Tech (Nano Technology) Entrance Exam Model Question paper of the Tezpur University, here I am uploading a pdf file having the same. There is descriptive type of the questions available. I have taken following questions from the attachment:

1. Rutherford’s model of the atom fails to explain
a) the neutral nature of atom b) the presence of a positively charged nucleus c) the heavy mass of the nucleus d) the stability of the atom

1. (a) Show that a free particle cannot absorb a photon completely. (3) (b) Explain why is Compton effect experimentally not observed for visible light. (c) An X-ray photon is found to have its wavelength doubled on being scattered through 90o. Find the wavelength and energy of the incident photon. (Compton wavelength of electron = 0.024 Ao). (3) 2. a) Using a d .c and a.c voltmeter to measure the output signal from a filter circuit, we obtain readings of 25 Vd.c and 1.5 Vrms. Calculate the ripple of the filter output voltage. (4) b) A.d .c voltage supply provides 60 v when the output is unloaded. When connected to a load, the output drops to 56 v. Calculate the values of voltage regulation.

Rests of the questions in the attachment, please click on it………………………
