W01 Q3 (c) (i) The correct directions please. ( no need for explanation.)
W09 Q7 P21 (a) Can you post how to correctly point out the angle of deviation.
S10 P21 Q5 (b) (ii) 2. (decreasing)
Thanx for any help!

Sorry but I won't have time to deal with the 1st question. :-[
Nov 09 P21
7. (a) After you have drawn the two directions, draw straight horizontal line from the particles A and B respectively. Then label each angle of deviation a and b for the specific particles.
Now you just have to mention that b < a
Jun 10 p21
b)(ii)2. Actually it should have been an arrow showing the decrease from positively charged sphere to the earthed metal plate or from the latter to the negatively charged sphere. Indicate the right direction using an arrow. ;)
Dania:
Refer to the attachment.
Please explain.

No problem. ;)
I assume you got the previous answers.
Change in K.E + Useful work done = Total k.E in overcoming friction + Change in P.E
1240 + 600 = Total k.E in overcoming friction + 1170
Total k.E in overcoming friction = 670 J
TJ-56:
On which formula is the one you stated based on?
thanx
