Question

Two graphs of the same harmonic wave are shown below. The graph (1) on the left shows the displacement of wave y, as a function of position x for a given instant of time. The graph (2) on the right shows the displacement of wave as a function of time 't' for a given position. The speed of the wave is

  1. 5.0 cms–1    
  2. 0.5 cms–1    
  3. 0.4 cms–1    
  4. 4.0 cms–1    

The correct answer is: 5.0 cms–1

A small bob attached to a light inextensible thread of length l has a periodic time T when allowed to vibrate as a simple pendulum. The thread is now suspended from a fixed end O of a vertical rigid rod of length fraction numerator 3 l over denominator 4 end fraction (as in figure). If now the pendulum performs periodic oscillations in this arrangement, the periodic time will be

A hollow conducting sphere of inner radius R and outer radius 2R has resistivity 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 V is applied between the two surfaces. Then, as perfectly conducting 'paint' and a potential difference 'r' increases from R to 2R, the electric field inside the sphere
