# An electric dipole is placed perpendicular to an infinite line of charge at some distance as shown in figure. Identify the correct statement.The dipole is repelled away from the line chargeThe dipole does not experience a forceThe dipole is attracted towards the line chargeThe dipole experiences a force as well as a torque

A
The dipole is repelled away from the line charge
B
The dipole does not experience a force
C
The dipole is attracted towards the line charge
D
The dipole experiences a force as well as a torque
Solution
Verified by Toppr

#### 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.
