Well this is what I did but not sure if it is correct.
B1 = UoI1/2pid = 4pi x 10^-7/2pi(.1) = 2 x 10^-5
B2 = 2 x 10^-5
B1 + B2 = Bp = 4 x 10^-5
b) B1 = 1 x 10^-5 and B2 = 1.5 x 10^-6
B1 distance is .10 m and B2 distance is .20 m
then i did B1 - B2 = Bp1 = 5 x 10^-6
c) B1 = UoI/2pi.30m =...
Okay, I figure out how to do this. For A i was suppose to find B1 and B2 then add them and it is going out of the page i believe.
For B it is going into the page and C is out of the page.
I didn't realize that I had to find the two B field. I was only thinking of one bar at a time when doing...

Okay, i finally got to working on this problem again with another classmate and came to this.
I am not sure if this is correct but this is what i came up with
Fm = Fe so,
qvB = qE
V = E/B
so I found the constant velocity which is 850/.910 = 934.07 m/s
after it travels into the reflector...
I decided to look at the equation again and look at this post again and now I am seriously confuse. I think I am going to find a tutor tomorrow to help me but I was told the physics tutor are not very helpful but I am going to give it a try anyways. BTW teacher emailed me back that she is not...
each time i read this i get more confuse.
I think I will wait till Tuesday to give this another try since I emailed the teacher and she said she will go over this with the class since I asked people in my class and they are all stuck at it also.
Thanks for the help and explanation.
I will be...
I am still a bit confuse and not really sure how i would draw a diagram for this. Today class did not even cover this either.
do i use this and solve for v? qvB = q(vB + E)? I know i just removed the x.
Thanks for the help so far, but when it comes to physics it takes me forever to understand it.
The formula given is a bit confusing. If I use F = q(vxB + E) I am still stuck because I do not know what F is. Would I have to set two equation together?
like: qvB = q(vxB + E)?
I just realize that will not work either since I do not know what x is.
Also I don't think we ever cover the...
Homework Statement
Consider the mass spectrometer shown schematically in Figure P19.30. The electric field between the plates of the velocity selector is 850 V/m, and the magnetic fields in both the velocity selector and the deflection chamber have magnitudes of 0.910 T. Calculate the radius...
Two capacitors, C1 = 25 µF and C2 = 6.0 µF, are connected in parallel and charged with a 150 V power supply.
(a) Calculate the total energy stored in two capacitors.
energy stored = 1/2C(deltaV)^2 or Q^2/2C
I been doing this and its marking me wrong.
first i found both charges which...
Its not so confusing but the given formula you wrote is new to me, since i have not seen that formula before.
I will give this problem another try hopefully when i get home today or during the weekend.
Thanks for the help and explanation.
