What happen when an electric dipole is placed in non uniform electric field?
When a dipole is placed in an electric field, the opposite charges on the dipole both experience a force due to the electric field. … Hence the dipole will experience both force and torque when placed in a non uniform electric field.
When an electric dipole P is placed in a uniform electric field?
An electric dipole of moment →p is placed in a uniform electric field →E. Then. (i) the torque on the dipole is p×E. (ii) the potential energy of the system is →p.
What is the direction of net force on an electric dipole placed in a non uniform electric field?
The direction of electric dipole moment is from negative to positive charge. Hence the resultant force will always be non-zero.
What happens when an electric dipole is placed in an electric field?
An electric dipole placed in uniform electric field experiences a torque which align the dipole parallel to the direction of the electric field with zero net force.
What will happen if electric field is not uniform?
No torque and no net force. … Now, for a non-uniform electric field there will be a torque on the dipole but also a net force. Once the dipole comes parallel to the electric field vector a force will act on the dipole in the direction of increasing field.
When an electric dipole P is kept in a uniform electric field E then for what value of angle between?
Hence, option (C) ⇒θ=0∘is the correct option.
When the dipole of dipole moment P is parallel to electric field E the torque experienced by it?
Torque is given as ζ = p E sinΘ
What is the direction of electric field of an electric dipole at a point on its axial line with respect to it’s electric dipole moment?
The direction of the electric field at an axial point of an electric dipole is same as that of its dipole moment and at an equatorial point it is opposite to that of dipole moment TLC.
What happen when an electric dipole is placed in non-uniform electric field what will be the force and torque on dipole when held parallel to direction of field?
So, when the electric field is not uniform then the net force will be non-zero and there will also be torque on the following system. If the dipole moment p is parallel or antiparallel to the external field E, the net torque is zero but there is a non-uniform force on the dipole E.
