In pursuit of these aims, grouped are formed and sectional interests emerge. As a result, policy decisions may serve the ends of political and career systems rather than those of the concern. In this way, the goals of the organisation may be displaced in favour of sectional interests and individual ambition. These preoccupations sometimes prevent the emergence of organic systems. Many of the electronic firms in the study had recently created research and development departments employing highly qualified and well paid scientists and technicians. Their high pay and expert knowledge were sometimes seen as a threat to the established order of rank, power and privilege. Many senior managers had little knowledge of technicality and possibilities of new developments and electronics. Some felt that close cooperation with the experts in an organic system would reveal their ignorance and show their experience was now redundant.31.

Increase the amount of electric current through it Vzii. Increase the number of turns of coil. V2OR(i) Activity:Take a coil of wire, AB, having a large number of turns and connect it to a galvanometer.Move the north pole of a strong bar magnet towards one end, B, of the coil. The galvanometer shows a momentary deflection indicating the presence of electric current in the coilAB.When the magnet is withdrawn / taken away from the coil, the galvanometer againshows momentary deflection in a direction, opposite to the first, indicating that thecurrent is set up in the opposite direction. 2Rule:Flemings right hand rule: stretch the thumb, forefinger and middle finger of right hand sothat these are perpendicular to each other. If the forefinger indicates the direction of themagnetic field and the thumb shows the direction of motion of the conductor, then themiddle finger will show the direction of current generated in the coil. 1ii. a) The galvanometer shows a momentary deflection (due to electric currentinduced in it) 1b) The galvanometer shows a momentary deflection (due to change in amountof electric current). 11. d2. b3. c4. b5. a6. c7. a8. c9. b10. b11. c12. d13. b14. d15. d16. b
