A long straight wire carries a charge with linear density `lamda`. A particle of mass m and a charge q is released at a distance r from the the wire. The speed of the particle as it crosses a point distance 2r is

Two point charges, each of mass m and charge q are released when they are at a distance d from each other. What is the speed of each charged particle when they are at a distance 2r ?
