How Do You Calculate the Magnitude of a Charge in a Magnetic Field?

AI Thread Summary
To calculate the magnitude of a charge in a magnetic field, the Lorentz force equation is essential. The force experienced by a charged body moving in a magnetic field is given by F = q(vB sin θ), where F is the force, q is the charge, v is the velocity, B is the magnetic field strength, and θ is the angle between the velocity and the magnetic field. In this case, with a velocity of 8.0 * 10^4 m/s, a magnetic field of 5.6 * 10^-5 T, and an angle of 30°, the charge can be calculated by rearranging the equation to q = F / (vB sin θ). It is important to refer to textbooks or reliable online resources for further clarification on applying the Lorentz force. Understanding these principles will aid in solving similar problems effectively.

Hello dave :welcome:

PF requires you do something yourself too; check the guidelines: no idea doesn't qualify. We understand you need help; make clear what help actually helps you.

In the mean time: check your notes and/or textbook, or Google Lorentz force

Lorentz's force is where you should begin.
 

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...
