Field theory questions asked in TRB 2017 EEE Paper

 


    Answer:
                    Electric flux density = Q ( charge contained by closed surface)
                    
                    Electric flux intensity= Q /рем0


                Answer: C
                                   
  •     force on Q inversely proportional to distance. So force wont vary linearly with   distance.
  •     Net force on Q3 is not zero.
