Here I am giving you question paper for Tamil Nadu common entrance test Physics And Materials Science examination in PDF file attached with it so you can get it easily.
There are 1 0 condensers each of capacity 89. If E is the kinetic energy of the material
5 The ratio between maximum and particle of mass m, then the de Broglie
minimum capacity obtained from these
condensers will be
1. 1 0 0 : 1
2. 6 0 : 9
3. 1 : 1 0 0
4. 1 : 5

Two bulbs, one of 5 0 watts and another of
25 watts are connected in series to the mains.
The current
1. through the 25 watt bulb is more
2. through the 50 watt bulb is more
3. is different in different bulbs
4. is the same in both the bulbs

A bar magnet is cut exactly a t the middle of
its length. The pole strength of the resulting
magnets
1. reduces to half its original value
2. increases twice to its original value
3. reduces to one fourth of its initial value
4. remains t h e same

88. The magnetic field a t a distance d from a
wavelength is given by

Existence of matter wave was experimentally
first demonstrated by
1. Newton
2. Planck
3. Davission and Germer
4.

When a n electron is accelerated, if
wavelength is 1 then t h e applied voltage is
nearly equal to
1. 15 Volts
2. 1 2 Volts
3. 500 Volts
4. 150 Volts

short bar magnet When the potential difference between t h e
transverse position are in the ratio
electrodes of a n X-ray tube is increased, i t
results in a n increase in
1. intensity
2. frequency
3. wavelength
4. speed of X - rays

T. invented The picture tube screens in television sets
1. He-Ne laser operate on
2. CO, laser 1. thermoluminescence
3. Ruby laser 2.
4. Nd: 3.
4. photoluminescence

We observe colours in thin films only because
1. thick films absorb light
2. reflection is possible only in thin films
3. interference condition is satisfied only
