A particle of mass 1 g and charge `2. 5 xx10^(-4) C` is released from rest in an electric field of `1.2 xx 10^4 NC^(-1)` (a) Find the electric force and the force of gravity acting on this particle. Can one of these forces be neglected in comparison with the other for approximate analysis? (b) How long will it take for the particle to travel a distance of 40 cm? (c) What will be the speed of the particle after travelling this destance? (d) how much is the work done by electric force on the particle during this period?
