M/j 2012, O/N 2012, Mj/ON 2011. :D
Thanks so much :)
I just didn't have time to solve many question papers at all because I had to study for my other exams!
I was panicking a lot. I still am. I just don't know what to do. I'm confused whether I should just revise all my notes and books or just stick with the question paper :/

Okay, I know that this is a really stupid question but I can't help but ask, how long should you take to finish section A of Paper 4 and section B?

I quote again. Someone please, help!

1st u shud find the gravitational force on the proton = weight = mg = 1.67 * 10^-27 * 9.81
gravitational force = 1.6 * 10^-27 N
then, find the electric force = F
we know that electric field strength = E = F/q
Also, E = V/d → F/q = V/d [formula on pg 136 of the coursebk]
So, F = qV/d
F = (1.6 * 10^-19 * 270) / (1.8 * 10^-2)
F = 2.4 * 10^-15 N

Comparing, electric force is very much gr8r than the gravitational force.
Fg is neglible. Hope u gt it!

Hi everyone, AsSalamoAlaikum Wr Wb...

To get things organized in a better way, I am making this thread. As othewise, some queries remain unanswered!

So post your PHYSICS doubts in this thread. InshaAllah other people here will help me and you all. :D ;)

NOTE: If any doubts in the pastpapers, please post the link! You can find links here!

Any Physics related notes and links will be added here in this post. Feel free to provide the links to your notes around the forum, or any other websites! :)
Thanks!
Jazak Allah Khair!

please can anybody give me summarised easy notes on "PSTN" and "MOBILE AND CELLPHONE NETWORK" from TELECOMMUNICATION in phy applications
I cant understand these two topics ...
Also if u have summarised notes(that have all necessary info) for the MEDICAL part of application,,please tell me that too !!!
URGENTLY,,PLEASE!
