PHYSICS P41.. how did it go??

[physx]

how did u find physics P41? how did u solve the first question about the glue thingy? did u take mg + m(w^2)r =18 ??

 

[1992]

yes it was like that, but i forgot that formula :S
what was the formula for electric potential energy?? and also gravitationall potential energy¿¿?

 

[physx]

well i used Gm1m2/r for GPE = (G(2*1.66*10^-27)^2)/r
and Q1Q2/4(pie)er for EPE = ((1.6*10^-9)^2)/4(pie)er

awesome ppr

yeah however i had a doubt in the power received at satellite as i got a very small number which is 1.8*10^-15 W. did u get the same answer?

I got that
Long paper, easier than expected.
Application so easy, I could do half of it.
I only wish I knew there were so many questions, I would have hurried. Missed 2.

i guess inshallah the thresholds will be low. i'd say something like 60 - 65.
what about the first question, did u get the angular velocity something like 7.73 ?
