Figure shows electric field lines in which an electric dipole P is placed as shown. Which of the following statements is correct ?

Answer»

The dipole will not experience any FORCE.
The dipole will experience a force TOWARD right
The dipole will experience a force toward left
The dipole will experience a force upwards

Solution : The place where electric field lines are close to each other, than electric field is strong and i they are away from each other, the electric fielc is weak.
`therefore` Electric field `E_(infty)at - q gt` electric field `E_(+)` at +q Electric force, `F =QE`
`therefore F prop E (therefore q)` are same
`therefore F_(-)/F_(+) = E_(-)/E_(+)`
But `E_(-) gt E_(+)`
`therefore` Resultant force F will be in direction of `F_(-)`It means towards left.
