Hi haruspex. Second part of the question here. Would appreciate any advice on this one. The only thing I can come up with is reversing the current of solenoid, but not sure how to prove this with the formulas.
The magnetic field is acting in a clockwise direction, which is why it pushes the electron the right side of the screen.
Hmmm, I know that E=Vq, therefore Vq=(1/2)mv2 so i need to find v.
Since the problem tells me the acceleration in the magnetic field, would I be able to use...
For d I am using the distance of the screen from the CRT, which is 1 meter.
For a, I am using the acceleration of the electrons in the magnetic field, which is 9.08 x 1014 m/s^2
v(final)2=v(initial)2 + 2ad
Initial velocity is 0 because it is at rest, so final velocity will be equal to whatever "2ad" turns out to be.
So E will look something like this
E = (1/2)m(2ad)2
Therefore, potential difference should be
V=E/q
V=((1/2)m(2ad)2)/q
I am unsure if it is okay if I use...
Homework Statement
A solenoid is placed beneath a CRT that produces a magnetic field of 1.10 x -2. The CRT is 1 meter away from a screen.
The electrons that make up the beam were accelerated from rest through a potential difference(V) at the beginning of the CRT. Acceleration of the electrons...
Alright. I figure the charge to mass ratio should be:
Fm=Fc
qvB = (mv2)/r
(q/m)=v/(Br)
When i crunch the numbers I get an answer of 1.7647 x 10 11
Same as an electron..what do you think of this?
Homework Statement
A Phosphorous 34 decays and emits a particle. A JJ Thomson experiment is done to find out the charge to mass ratio of this particle. The particle moves undeflected through mutually perpendicular magnetic and electric fields of 2.00 x 10-3 T and 1.08 x 104 N/C, respectively...
Could I use the total kinetic energy to find the mass defect by manipulating e=mc2? If so, once I find the mass defect, can I add that mass to the mass of He4 and the neutron to get the mass of He5?
KE of He5 would be 0 since the problems states it at rest before the reaction.
KE of He4 is given to us.
KE of Neutron could be found using KE=mv2/2. The mass is given to us in the question, and we already found velocity.
Ok, so what do i do when I found the KE? Am i going to be using E=mc2?
Would total KE after fission be equal to KE of He4 plus the KE of the neutron?
To find the KE of the neutron would I be able to just use mv2/2? Since I already found the velocity of the neutron in the previous question?
