LAB PREP #5

did anyone get #4 and 5 and the equation for v?

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 =

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)))

for #1, e/m=(2*V)/(B^2*r^2)

did anyone get #3,4,and 5?

#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?

a=((a_v1+a_v2)+(a_h1+a_h2))/4

dont know about delta 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?

a=((a_v1+a_v2)+(a_h1+a_h2))/4

dont know about delta a...

Can someone please help with number 4 and 5? or the second part of #3 deltaA?

2*(sqrt((Deltar/r)^2))

For number 4 I thought it would be this, but its not working... Suggestions

delta a = delta d

anyone got #4 and 5

thanx

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!

#4:
2*(Deltar/r)*((I*r)^2)
