sweetie:
Thank You soooo much A.F ;)
+rep

cud u also xplain the rest of the questions???????/

~ A.F ~:
my bad ;D

Q.33: u must find V1 and V2

V1: same resistence..therefore V1 across PS = 2/2= 1.0 V

V2: 3 ohms: 2 ohms: 5ohms
      x voltage:       : 2

do ratio..now x=3x2/5= 1.2

therefore V1-V2= -0.2 V----> answer is C

Q 37: Same resistors, same length, same material ---> C

Q29: Its exactly like a projectile..constant speed as its in vaccum..no rsistence, and acceleration upwards as its negatively charged..attracted upwaqrds towards the +ve plate

got that?  ::)

~ A.F ~:
and Thanks 4 the + rep. ;D

sweetie:
for Q33, why did u take the ratio's???
and Q37> in resistor Q arent the wires in parallel , so the total resistance should be x/7????

nid404:
Q33...current divides on the basis of the ratio of the resistance...

Q37 srry I can't explain :-[
