Question

A capacitor of capacitance C0 is charged to a potential V0 and then isolated A small capacitor C is then charged from C0 , discharged and charged again; the process being repearted n times Due to this, potential of the larger capacitor is decreased to V. Value of C is :

  1. C subscript 0 end subscript open square brackets V subscript 0 end subscript divided by V close square brackets to the power of 1 divided by n end exponent    
  2. C subscript 0 end subscript open square brackets open parentheses V subscript 0 end subscript divided by V close parentheses to the power of 1 divided by n end exponent minus 1 close square brackets    
  3. C subscript 0 end subscript open square brackets open parentheses V divided by V subscript 0 end subscript close parentheses minus 1 close square brackets to the power of n end exponent    
  4. C subscript 0 end subscript open square brackets open parentheses V divided by V subscript 0 end subscript close parentheses to the power of n end exponent plus 1 close square brackets    

The correct answer is: C subscript 0 end subscript open square brackets open parentheses V divided by V subscript 0 end subscript close parentheses minus 1 close square brackets to the power of n end exponent

A narrow monochromatic beam of light of intensity I is incident on a glass plate as shown in figure. Another identical glass plate is kept close to the first one and parallel to it. Each glass plate reflects 25% of the light incident on it and transmits the remaining. Then the ratio of the maximum to minimum intensities in the interference pattern formed by the two beams obtained after one reflection at each plate is
