1 июл. 2015 г. · To be more quantitative, suppose the negative charge is at r and the positive charge at r+dn. The total force is then F=q[E(r+dn)−E(r)].

24 авг. 2021 г. · The electric force on a dipole is F=(p⋅∇)E, where p is the dipole moment, E is the electric field, and ∇ is the gradient operator.

1 мар. 2016 г. · The Lorentz Force does apply to an electric dipole. An electric dipole is two charges of charge ±q separated by a distance d=p/q.

18 нояб. 2012 г. · When an electric dipole of moment P is located in a non-uniform electric field E, there is an net force exerted on it.

29 мар. 2015 г. · Why is force exerted by a charged wire on a dipole given as F=P×(dE(r))/(dr) where P is the dipole moment?

11 июл. 2017 г. · In a uniform electric field, the net force on an electric dipole is zero because the force on opposite poles acts in opposite directions.

6 нояб. 2017 г. · where α is an angle between dipole axis and the position vector of the charge. So the force will be F=qE=1 ...

25 февр. 2019 г. · For an electric dipole of dipole moment →p placed in an electric field →E experiences a force given by →F=−∇U=−∇(→p⋅→E)=(→p⋅∇)→E.

21 янв. 2015 г. · The way to do this is the same as you find the field for the first dipole: find the net force on the two charges of the second dipole, and then take the limit.

15 мая 2020 г. · Think of a “finite-size dipole” as a positive charge at the tip of the p vector and an equal negative charge at the tail. The forces exerted by ...
