An electric dipole is placed perpendicular to an infinite line of charge at some distance as shown in figure. Identify the correct statement.

Question

Answer 1

The direction of dipole is from negative charge to positive charge.
So from figure, the -ve charge of dipole is nearer to infinite line of charge than the +ve charge of dipole.
so, the force on -ve charge of dipole towards line charge is more than that on +ve charge of dipole away from the line charge. So net force on dipole is towards the line charge.
So option A is correct and B and C is incorrect.
The net force is along the axis of dipole so there is no torque produced due to this force.
So option D is incorrect.

Answer 2

The direction of dipole is from negative charge to positive charge.

So from figure, the -ve charge of dipole is nearer to infinite line of charge than the +ve charge of dipole.

so, the force on -ve charge of dipole towards line charge is more than that on +ve charge of dipole away from the line charge. So net force on dipole is towards the line charge.

So option A is correct and B and C is incorrect.

The net force is along the axis of dipole so there is no torque produced due to this force.

So option D is incorrect.
