Some questions is given here.

Q1. A magnet is moving towards a coil with a uniform speed as shown in the
figure. State the direction of the induced current in the resistor

Q2. A square coil, OPQR, of side a, carrying a current I, is placed in the Y-Z plane as
shown here. Find the magnetic moment associated with this coil.

Q3. Give one example each of a ‘system’ that uses the
(i) Sky wave (ii) Space wave mode of propagation

Q4. A concave mirror, of aperture 4cm, has a point object placed on its principal axis
at a distance of 10cm from the mirror. The image, formed by the mirror, is not
likely to be a sharp image. State the likely reason for the same.

Q5. Two dipoles, made from charges q and Q, respectively, have equal dipole
moments. Give the (i) ratio between the ‘separations’ of the these two pairs of
charges (ii) angle between the dipole axis of these two dipoles.

Q6. The graph, shown here, represents the V-I characteristics of a device. Identify the
region, if any, over which this device has a negative resistance.

Q7. Define the term ‘Transducer’ for a communication system.

Q8. State the steady value of the reading of the ammeter in the circuit shown below.

Q9. The following table gives data about the single slit diffraction experiment:
Wave length of Light Half Angular width of the principal maxima

Find the ratio of the widths of the slits used in the two cases. Would the ratio of
the half angular widths of the first secondary maxima, in the two cases, be also
equal to q?
