Here I am giving you question paper for Electronics and Telecom Engineering stream exam of Indian Engineering Services

6. A flux of 1.2 mWb exerts in a magnet
having a cross-section of 30 cm2.
The flux density in tesla is
(b) 0.4
(c) 2.5 a

7. If the drift velocity. of holes under
a field padient of 200 V/m is
100 m/s, their mobility in SI units
is
(a) 0.5
(b) 0.05

8. A bar magnet made of steel has a
magnetic moment of 2.5 ~ - r n ~ and
a mass of 6.6~ lo3 kg. If the
density of steel is 7.9 x lo3 kg/rn3,
the intensity of magnetization is
fa) 8.3~10~' A/m
(b) 3 x lo6 A/m
(c) 6.3x10-~ A/m
(d) 8.2 x lo6 A/m

9. An ideal low-pass filter has a cut- off frequency of 100 Hz. If the
input to the filter in volts is
v(t) = 3 m s i n 1256t, the magnitude
of the output of the filter will be
(a) o v
(b) 20 v
(c) 100 v
(d) 200 v

10. Superconductors are becoming
'popular for their use in
generating very strong
magnetic field
manufacture of bubble
memories
generating electrostatic fieId
generating regions free from
magnetic field
The space between the plates
of a parallel-plate capacitor of
capacitance C is filled with three
dielectric slabs of identical size as
shown in the figure. If dielectric
constants are E~ and c3, the new
capacitance is
