2- They wouldnt have given you the value, never seen CIE do sth like that from year 2000 Examinations :P
What do you think?

Valid point.
I may have overthought this a bit too much. Thanks :P
SkyPilotage:
yup, tell me abt it! I hate it when I do that :P
mess up all the easy questions and solve the hard ones fluently :D

Attachment 11.JPG:
I= Q/T
Q=ne
Therefore I= N(e)/t => I/e = N/t
Since rate of flow = N/t , I/e = N/t
Rate of flow = I/e
Rate of flow = 4.8/ 1.6x10^-19 = 3.0 x 10^-19 s^-1
Electrons flow from negative to positive terminal so there flow of electron is in the direction Y to X
Answer = C
-----------------------------------------------------------------------------------------------------------
Attachment 5.JPG
Anticlockwise moment = Clockwise moment
10 x 0.6 + 100 x 0.1 = 20 x 0.4 + 20 x d
d = 0.4 m from pivot so answer is D
-----------------------------------------------------------------------------------------------------------
Will solve the others later...
