Will you please give here sample question paper of Physics subject for Indian Administrative service (IAS) examination ?

As you requires here I am giving you sample question paper of Physics subject for Indian Administrative service (IAS) examination.

Sample paper:

An electric field of I 00 V /m is applied to a sample bf n-type semiconductor whose Hall
coefficient is -0.0125 m3/coulomb. Determine the current density in the sample assuming
6

What are the magic numbers in nuclei ? List the experimental evidences indicating their
existence.

What is the reciprocal lattice and why is it named so ? Derive the relationships for the
primitive translation vectors of the reciprocal lattice in terms of those of the direct lattice.

How are elementary particles classified on the basis of their participation in fundamental
Interaction?

i)How does liquid drop model explain fission ?

ii)What are the limitations of shell model

iii) What are salient features of nuclear forces ?

(iv) Discuss Yukawa's theory of nuclear forces?
