124, 11 c) - Could you please help and give any hints on it?
124, thanks a lot, you the man. )
124, i have E and B correct but pointing vector with formula E*B/mu_0, mu_0 = 4*pi*10^(-7), incorrect. pliz, tell where is error?
it's correct ?
8 e) poling vector = E*B/mu_0 = ??
11 b) q*9*(10^9)/r^2 r = distance from the origin
I think drawings at all identical so don't worry
prob 8
denaminator may be different, it depends on drawing
me, a = lambda/0.5 d = lambda/0.125
me, I will exchange solution 8 on 7)
Jack, did you solve anything else from this list: 11 c) 10 b) 8 d,e,f) 5 b,d)
S = pi(b^2 - a^2)
8 a) E = (st)/(S*E_0) S = Area 8 b) E*d 8 c) C = E*E_0*S/d
11 a) q/(4*pi*E_0*(r^2)*k) 11 b) q*k/(r^2) 11 d) 0
Anyone, can help with questions: 11 c) 10 b) 8 d,e,f) 5 b,d,e)
10, b) how to solve
thank you, but since it has to be in kg, do i do the same thing but with 0.5*1.54=0.77 0.5*0.77*2.50^2 = 2.406 kgm^2/s
I've been trying that and I'm still not getting the right answer
