Deflection due to Magnetic Field

AI Thread Summary
The discussion revolves around calculating the deflection of an electron beam in a tube TV set due to magnetic forces, with a potential difference of 30,000V and a known charge to mass ratio. Participants express confusion about the term "end of the magnetic field region" and its implications for solving the problem. There is also a mention of missing information regarding the required magnetic field to achieve a specific deflection. The equations provided include the radius of curvature and a formula involving the electric potential. Overall, clarity on the magnetic field's role and additional data is needed to proceed with the calculations.

Homework Statement


The deflection of the electron beam in an old-fashioned tube TV set is accomplished by magnetic forces. Each electron is accelerated through a potential difference of V=30000V. The charge to mass ratio of the electron is 175824175824.176C/kg.

If there is a x2=0.1m gap between the end of the magnetic field region and the end of the tube, how far from the center of the screen does the beam strike?

ynet = y1 + y2 =


Homework Equations


R = mv/qB

R = (m/eB)*√(2eVacc/m)


The Attempt at a Solution


I'm not even sure where to begin. The first thing I'm confused by is what do they mean by end of magnetic field region?

Im having the same problem as above with the same question.
it just that the question above seem to be missing a line of information which is
What magnetic field is required to produce a deflection of y1=0.03m if the magnetic field region is x1=0.065m long?
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
