Question

An electromagnetic wave travelling in a lossless dielectric medium having a dielectric constant €, = 9, has the electric field, E, = E, sin (kz — 2 x 10%) Vm™ where E; is the amplitude and k is the wave vector. Among the following options, the incorrect choice is :

Options

  1. 1The speed of the electromagnetic wave inside the medium is 10° ms™
  2. 2The wavelength of the electromagnetic wave inside the medium is 300 m
  3. 3The magnetic field is given by the relation B, = Zo gin(le-2rx10° t) where v is the speed of the electromagnetic wave inside the medium
  4. 4The direction of propagation of the electromagnetic wave is along +z

Supplied answer marker

Option 2 - The wavelength of the electromagnetic wave inside the medium is 300 m

Consider two circuits, (A) and (B), each having two resistors. One of them has a positive temperature coefficient of resistance, +a, while the other one has a negative temperature of coefficient, — a, as shown in the figure. The current through these circuits are denoted by [, and I. At initial temperature, the resistance of the two resistors is R,. As the temperature is increased, the correct option that describes the variation of current in these circuits is : \Y I, \Y I, a. R,1-0AT) R1+0AT) ’ R (1+aAT) @) ‘B®
