ooops i didn't see that they stick togther so one v will be negative but that is the base forumla you should use
hope it helped

they don't stick together

Which paper?

q.19 of wich year?

sorry

u dont need k here.
simply use 1/2Fx!

0.5FE = 0.5 * 0.40 * 2
= 0.40 J

k = 2/0.40 = 5

1/2 * 5 * 0.40 * 0.40 = 0.40 J

I used both formulas. Both gave the same answer. But I recommend using the one which requires less working (over here 1/2 * Fe).

0.5FE = 0.5 * 0.40 * 2

k = 2/0.40 = 5

hey will u look at q.7.
as the ball is thrown horizontally, it will follow a parabolic path ryt? so shouldnt the horizontal component ov velocity remain constant??

aah why did u divide .40 by 2??

Q no 11 and 13 too plz

 

[omg]

aah why did u divide .40 by 2??

because 2N is the force!

 

[applepie1996]

omg can i explain q15 tomorrow

 

[hmlahori]

its charge to mass ratio. and dats part of A2!!!

Well ok thanks. Can you explain the other questions?

 

[omg]

omg can i explain q15 tomorrow

okay

 

[USMAN Sheikh]

ANYONE PLS RESPOND TO MY QUESTIONS ON PAGE 38 written in yellow and red big fonts plsssss need help

 

[USMAN Sheikh]

red fonts question on page 41 and on page 38 (normal fonts )pls any one repond to that plsssss andy one plsss

 

[MysteRyGiRl]

okay

could u help me out plz...hv posted my questions in da previous post and also plz explain where u said 2N is da force...

 

[USMAN Sheikh]

leosco1995 pls where are u ??

Q no 11 and 13 too plz

for q.11,
first u can find the mass using F=mg
20N=m10
so mass=2kg
now the net force in (10-4=6N)
so, 6=2 x a
a=3! hence C!!

 

[applepie1996]

lesco thanks alot man u r doing a great job few more questions for u kindly solve them pls
q 14 and 36 of june 11 variant 11
q 26 28 36 of november 11 variant 11

Q14)1/2mu^2=mgh
m gets cancelled so u^2=2gh take 2g as k which is constant
so h is divide by 2 so u^2/root of 2
so v^2=u^2/root2
so 1/root2
dunt noe if its correct just did it
