Magnetic and electric fields combined Help

AI Thread Summary
An electron with a velocity of 1.90 km/s in the positive x direction and an acceleration of 2.00 E12 m/s^2 in the positive z direction is analyzed under uniform electric and magnetic fields. The electric field strength is given as 20.0 N/C in the positive z direction. The discussion highlights that the magnetic field component in the x direction can be any value, while the participant is uncertain about the overall motion and interaction of the electric and magnetic fields. The participant expresses confusion about the relationship between the electric field and the magnetic field but ultimately resolves their query. Understanding the dynamics of charged particles in these fields is crucial for solving such physics problems.

Homework Statement


An electron has a velocity of 1.90 km/s (in the positive x direction) and an acceleration of 2.00 E12 m/s^2 (in the positive z direction) in uniform electric and magnetic fields. If the electric field has a magnitude of strength of 20.0 N/C (in the positive z direction), determine the following components of the magnetic field. If a component cannot be determined, enter 'any value' or 'not applicable' - whichever is most appropriate.

B(x direction):
B(y direction):
B(z direction):

Homework Equations


F=qvBsin(theta)
F=ILB
sum of forces=(mass)(centripetal acceleration)
There may be some others as well.

The Attempt at a Solution



Well, I know that B(x direction) can be any value. I am assuming that the motion of the particle is circular, and it is in the z-plane. Is this right?

I really don't even know where to start on this, and I have to submit it to my teacher by midnight, and the book doesn't explain anything like this. How does the electric field affect the magnetic field?

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...
