An electric dipoleof dipole moment p is kept at a distance r from an infinite long charged wire of linear charge density lambda as shown. Find the force acting on the dipole. |
|
Answer» SOLUTION :Field intensity at a distance r from the line of charge is `E=(lambda)/(2pi in_(0)r)` The FORCE on the dipole is `F=rho(DE)/(dr)` `=p[(-lambda)/(2pi in_(0)r^(2))]= -(p lambda)/(2pi in_(0)r^(2))` Here the net force on dipole due to the wire will be ATTRACTIVE. |
