the gravitional force will always reamin constant throughout the fall.so they told to take the vertically force upwards.so accleration is negative

amphorous

here you go

thanx soo much just a few doubts:
in qn 1.) why do they do S2X-S1X ??
and this (n+1/2)lambda and n x lambda........are they formulas we need to know?? and what exactly is 'n'?
qn 2.) when i do (3/100 x 327.66) i get 98.3 while u have written 10
thanx again

anyone here knows how to solve mcq 35 of o/n 2004??

apply krichroff's law so the current passes through r is 2.then q=it.u wull get 10a

u will get 9.8.i didnt apply any formula just take uncertaininty in 2 sf.so u wull get the ans

http://www.xtremepapers.com/papers/...nd AS Level/Physics (9702)/9702_w11_qp_12.pdf Q26 anyone? pleeease i'm desperate! :'(

do it by this 1
180/18=45/x
u will get 45 by multiplying 1/8*180

yes those are formula n is like a constant and its integers like 0,1,2,3,4,5,6,7.......
and it come 9.83 you rounded to 1 sf equal to 10

anyone plz tell me mcq 32 of oct nov 2011 v 11????????

anyone plz tell me mcq 32 of oct nov 2011 v 11????????

i think the ans is c.no resultant force is acting.as it is moving frm positive to negative so it will be anticlockwise
