Two fixed charges 4Q (positive) and Q (negative) are located at A and B, the distance AB being 3 m.
                    
  • a)
    The point P where the resultant field due to both is zero is on AB outside AB.
  • b)
    The point P where the resultant field due to both is zero is on AB inside AB.
  • c)
     If a positive charge is placed at P and displaced slightly along AB it will execute oscillations.
  • d)
     If a negative charge is placed at P and displaced slightly along AB it will execute oscillation.
Correct answer is option 'A,D'. Can you explain this answer?
Verified Answer
Two fixed charges 4Q (positive) and Q (negative) are located at A and ...
(A) electric field due to positive charge is away from it and electric field due to negative charge is towards it so there cannot be a point on AB where electric field can be zero
(D) negative charge will experience a repulsion force due to −ve charge and attraction force due to +ve charge, so if pushed away from charges then a net attractive force and if pushed towards AB then a net repulsive force will be there so there will be oscillations.
