Question

A light ray gets reflected from a pair of mutually perpendicular mirrors, not necessarily along axes. The intersection point of mirrors is at origin. The incident light is along y = x + 2. If the light ray strikes both mirrors in succession, then it may get reflected finally along the line:

  1. y = 2x – 2    
  2. y = – x + 2    
  3. y = – x – 2    
  4. y = x – 4    

The correct answer is: y = x – 4

A slab of high quality flat glass, with parallel faces, is placed in the path of a parallel light beam before it is focussed to a spot by a lens. The glass is rotated slightly back and forth from the vertical orientation, about an axis out of the page as shown in the figure. According to ray optics the effect on the focussed spot is:

A ball of mass m is attached to a rigid vertical rod by means of two massless strings with length L. The strings are attached to the rod at points a distance L apart (see Figure). The system is rotating about the axis of the rod, both strings being taut and forming an equilateral triangle. The tension in the upper string is T1

A hollow conducting sphere of inner radius R and outer radius 2R has resistivity 'rho' a function of the distance 'r' from the centre of the sphere: rho equals k r to the power of 2 end exponent divided by R. The inner and outer surfaces are painted with a perfectly conducting 'paint' and a potential difference capital delta V is applied between the two surfaces. Then, as 'r' increases from R to 2R, the electric field inside the sphere
