ques 1
anyone figure out how to do this part?
Subsitute the equation for the velocity v into the equation for the radius r and then solve for e/m in terms of the accelerating voltage V and the magnetic field B.
e/m =

Re: LAB PREP #5
Question 1:
KE = (q*V)
v = sqrt((q*V)/(.5*m))
r= (m*v)/(q*B)
e/m = ?
and I didnt get the last part of that yet
Question 2:
B = 2*pi*k*(I/a)
B = N*(2*pi*k*(I/a))
B = 2*(N*(2*pi*k*(I/a)))
KE = (q*V)
v = sqrt((q*V)/(.5*m))
r= (m*v)/(q*B)
e/m = ?
and I didnt get the last part of that yet
Question 2:
B = 2*pi*k*(I/a)
B = N*(2*pi*k*(I/a))
B = 2*(N*(2*pi*k*(I/a)))

#3)
a=(1/2)*((2*a_v1)+(2*a_v2)+(2*a_h1)+(2*a_h2))/4
I can't get the 2nd part of #3 (deltaa), #4 or #5... can anybody help me?

2*(sqrt((Deltar/r)^2))
For number 4 I thought it would be this, but its not working... Suggestions

#4&5
Working on these 2 for 2 1/2 MF'in hours!!! I thought the labs were supposed to take less time. When/if I get it, I will post it. Studying for other exams  I DON'T THINK SO!

For #5 I entered this:
(sqrt((Deltas/s)^2 +(Deltaa/a)^2))*(e/m)
and it is incorrect, can anyone help me
(sqrt((Deltas/s)^2 +(Deltaa/a)^2))*(e/m)
and it is incorrect, can anyone help me
pleasehe Guest
nevermind got it
nevermind i got it
#5
delta(e/m)=sqrt((Deltas/s)^2+(2*Deltaa/a)^2)*(e/m)
#4
2*(Deltar/r)*((I*r)^2)
#5
delta(e/m)=sqrt((Deltas/s)^2+(2*Deltaa/a)^2)*(e/m)
#4
2*(Deltar/r)*((I*r)^2)

#5
my bad... yeah it does. i entered the whole thing without realizing that the answer was just:
#5: sqrt((Deltas/s)^2+(2*Deltaa/a)^2)*(e/m)
thx
#5: sqrt((Deltas/s)^2+(2*Deltaa/a)^2)*(e/m)
thx
