Group - ‘A’ Attempt Any Three question. [3*6]
1. State
and prove principle of conservation of linear momentum.
2. What
is simple pendulum? Show that the motion of simple pendulum is simple harmonic
and hence find its time period.
3. Define
minimum deviation Produced by prism. Hence derive the relation

case of Newton's second law of motion.
6. Show
that g decreases with increase in height.
7. State
and explain Stefan's law of black body radiation.
8. Show

9. Define
critical angle and total internal reflection of light.
10. Define lens formula. Derive lens formula for
convex lens.
11. Differentiate among diamagnetic, paramagnetic
and ferromagnetic materials.
Group - ‘C’ Attempt Any Six question. [6*4]
12. A slab of mass 10kg is laying on a plane
inclined at 30º to the horizontal. Find the least force which will pull the
slab upward (µ=0.15).
13. A constant torque of 200 Nm, turns a wheel about
its center. The moment of inertia about this axis is 100 kgm2. Find
the angular velocity gained in 4 Second used also calculate the kinetic energy
gain0 after 20 revolutions.
14. Find the result of mixing 20 gm of water at
90°c with 5gm of ice at -10°C. (Sp. heat of ice=0.5 calg-1 ºC-1,
sp. heat of water= 1 calg-1 ºC-1, Latent heat of fusion
of ice=80 calg-1)

of radius of curvature 16 cm. Find the position of image and magnification of
mirror.
16. Find the minimum deviation produced by an equilateral
glass prism of refractive index 1.5.
17. A bar magnet 10cm long is placed in the magnetic
meridian with its N-pole pointing geographical north. A neutral point observed at
a point 15cm from each pole. Calculate its magnetic moment.
18. The total intensity of earth's magnetic field
at a place where the angle of dip 30º is 37x10-6 T. Find the horizontal
and vertical components.
