### Sample Questions

Question 1
Which of the following statements is correct for any thermodynamic system?
 The change in entropy can never be zero. The work done in an adiabatic process is always zero. Internal energy and entropy are state functions The internal energy changes in all processes.
Question 2
A radiation of energy E falls normally on a perfectly reflecting surface. The momentum transferred to the surface is
 Ec E/c2 2E/c E/c
Question 3
A plane convex lens of refractive index 1.5 and radius of curvature 30 cm is silvered at the curved surface. Now this lens has been used to form the image of an object. At what distance from this lens an object be placed in order to have a real image of the size of the object?
 80 cm 20 cm 30 cm 60 cm
Question 4
The maximum number of possible interference maxima for slit-separation equal to twice the wavelength in Young’s double-slit experiment is
 zero three infinite five
Question 5
An electromagnetic wave of frequency ν = 3.0 MHz passes from vacuum into a dielectric medium with permittivity ε = 4.0. Then
 wavelength is doubled and the frequency remains unchanged wavelength is halved and frequency remains unchanged wavelength is doubled and frequency becomes half wavelength and frequency both remain unchanged.
Question 6
Two spherical conductor B and C having equal radii and carrying equal charges in them repel each other with a force F when kept apart at some distance. A third spherical conductor having same radius as that of B but uncharged brought in contact with B, then brought in contact with C and finally removed away from both. The new force of repulsion,between B and C is
 F/8 3F/8 F/4 3F/4
Question 7
A charged particle q is shot towards another charged particle Q which is fixed, with a speed v it approaches Q upto a closest distance r and then returns. If q were given a speed 2v, the closest distances of approach would be
 2r r/4 r/2 r
Question 8
Alternating current can not be measured by D.C. ammeter because
 A.C. changes direction D.C. ammeter will get damaged. average value of current for complete cycle is zero A.C. cannot pass through D.C.
Question 9
The resistance of the series combination of two resistances is S. When they are joined in parallel through total resistance is P. If S = nP, then the minimum possible value of n is
 1 3 4 2
Question 10
An electric current is passed through a circuit containing two wires of the same material, connected in parallel. If the length and radii of the wires are in the ratio of 4/3 and 2/3, then the ratio of the currents passing through the wire will be
 41277 3 41495 2
