Question

A particle of mass 1 kg & charge fraction numerator 1 over denominator 3 end fraction mu C is projected towards a non conducting fixed spherical shell having the same charge uniformly distributed on its surface. Find the minimum initial velocity of projection required if the particle just grazes the shell.

  1. square root of fraction numerator 2 over denominator 3 end fraction end root m divided by s    
  2. 2 square root of fraction numerator 2 over denominator 3 end fraction end root m divided by s    
  3. fraction numerator 2 over denominator 3 end fraction m divided by s    
  4. none of these    

The correct answer is: square root of fraction numerator 2 over denominator 3 end fraction end root m divided by s

All the boron trihalides except B may be prepared by direct reaction between the elements Boron trihalides consist of trigonal - planar BX3 molecules Unlike the halides of the other elements in the group they are monomeric in the gas, liquid and Sol. id states, BF3 and BCl3 are gases, BBr3 3Iis a volatile liquid and B is a Sol. Id Boron trihalides are Lewis acids because they form simple Lewis complexes with suitable bases, as in the reaction : B F subscript 3 end subscript left parenthesis g right parenthesis plus colon N H subscript 3 end subscript left parenthesis g right parenthesis ⟶ F subscript 3 end subscript B minus N H subscript 3 end subscript left parenthesis s right parenthesis However, boron chlorides, bromides and iodides are susceptible (sensitive) to protoly sis by mild proton sources such as water, alcohols and even amines; for example BCl3 undergoes rapid hydrolysis: B C l subscript 3 end subscript left parenthesis g right parenthesis plus 3 H subscript 2 end subscript O left parenthesis l right parenthesis ⟶ B left parenthesis O H right parenthesis subscript 3 end subscript left parenthesis a q right parenthesis plus 3 H C l left parenthesis a q right parenthesis It is supposed that the first step in the above reaction is the formation of the complex C l subscript 3 end subscript B leftwards arrow O H subscript 2 end subscript which then eliminates HCl and reacts further with water
