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 ?

Two point charges each of magnitude +q are placed at a distance r from each other. Draw the lines of force in this case.

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

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 charge each Q are released when the distance between is d .Then the velocity of each charge of mass m each when the distance between them is 2d is

Two identical charges, 5 muC each are fixed at a distance 8 cm and a charged particle of mass 9 xx 10^(-6) kg and charge -10 muC is placed at a distance 5 cm from each of them and is released. Find the speed of the particle when it is nearest to the two charges.
