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?

A boy puts a heavy box of mass M of his head and jumps down from the top of a multistoried building to the ground. How much is the force exerted by the box on hishead during his free fall? Does the for greatly increase during the period he balances himself after striking teh ground?

(a) In the above example, the electron drift speed is estimated to be only a few mm s^(-1) for currents in the range of a few amperes, How then is current established almost the instant a circuit is closed? (b)The electron drift arises due to the force experienced by electrons in the electric fieldinside the conductor. But force should cause acceleration. Why then do the electrons acquire a steady average drift speed? If the electron drift speed is so small, and the electron's charge is small, how can we still obtain large amounts of current in a conductor? (d)When electrons drift in a metal from lower to higher potential, does it mean that all the "free' electrons of the metal are moving in the same direction? (e) Are the paths of electrons straight lines between successive collisions (with the positive ions of the metal) in the (i) absence of electric field, (ii) presence of electric field?
