A point charge is moving along a straight line with a constant velocity v. Consider a small area A perpendicular to the direction of motion of the charge . Calculate the displacement current through the area when its distance from the charge is x. The value of x is not large so that the electric field at any instant is essentially given by Coulomb's law.

A charged particle of charge 2 muC and mass 10 milligram, moving with a velocity of 1000 m//s enters a uniform electric field of strength 10^(3) N//C directed perpendicular to its direction of motion. Find the velocity and displacement of the particle after 10s .

An infinite line cahrge is perpendicular to the plane of the figure having linear charge density lamda , A partcle having charge Q and mass m is projected in the field of the line cahrge fromo point P. the point P is at a distance R from the line cahrge and velocity given tot he particle is perpendicular tot he radial line at P (see figure) (i). Find the speed of the particle when its distance from the line cahrge grows the etaR(eta gt 1) (ii). Find the velocity component of the particle along the radial line (joining the line charge to the particle) at the instant its distance becomes etaR .
