Question

Two magnets A and B are identical and these are arranged as shown in the figure. Their length is negligible in comparison with the separation between them. A magnetic needle is placed between the magnets at point P which gets deflected through an angle theta under the influence of magnets. The ratio of distances d1 and d2 will be

  1. left parenthesis 2 c o t invisible function application theta right parenthesis to the power of 1 divided by 3 end exponent    
  2. left parenthesis 2 t a n invisible function application theta right parenthesis to the power of negative 1 divided by 3 end exponent    
  3. left parenthesis 2 c o t invisible function application right parenthesis to the power of negative 1 divided by 3 end exponent    
  4. left parenthesis 2 t a n invisible function application theta right parenthesis to the power of 1 divided by 3 end exponent    

The correct answer is: left parenthesis 2 c o t invisible function application theta right parenthesis to the power of 1 divided by 3 end exponent
