Questions (page 2)

Section A

Q1.

(a) Determine the eigen vectors of the matrix \beginvmatrix -2 & 2 & -3 \\ 2 & 1 & -6 \\ -1 & -2 & 0 \endvmatrix Show that those eigen vectors are linearly independent.

(b) Discuss superconductivity, superconducting materials and their applications.

(c) Find the force with which the plates of a parallel-plate capacitor attract each other. Also determine the pressure on the surface of the plate due to the field.

(d) Find the z parameters of the network shown in the figure. Is the network reciprocal? If so why? Assume the operational amplifier is ideal.

(e) Volume charge density is the same as the divergence of the electric flux density. Using Gauss's law, derive equations to prove it.

Section A

Q2.

(a) Find the difference between the values of ∫ \phi d\vecr, \phi(x, y) = x3y + 2y from (1, 1, 0) to (2, 4, 0) along the curve y = x2, z = 0 and along the straight line joining (1, 1, 0) and (2, 4, 0). Hence evaluate ∫ (\nabla \cdot \vecf)d\vecr, where \vecf = 1/4x4y\hati + y2\hatj + xy\hatk along the curve which is a parabola y = x2, z = 0 from (1, 1, 0) to (2, 4, 0).

(b) (i) State Hall effect and discuss the applications of Hall effect.
(ii) A flat silver strip of width 1.5 cm and thickness 1.5 mm carries a current of 150 amperes. A magnetic field of 2.0 Tesla is applied perpendicular to the flat face of the strip. The emf developed across the width of the strip is measured to be 17.9 \muV (Hall effect). Estimate the number density of free electrons in the metal.
