AI Thread Summary
The discussion revolves around solving for the velocity vector, $\vec{\upsilon}$, using provided equations and a diagram. The initial attempt involved calculating $\vec{\upsilon}$ with the formula $\vec{\upsilon} = \vec{\Delta} V / (B d)$ and resulted in an incorrect value for B. A user noted that their link to the diagram was not functioning, which hindered responses. Ultimately, the problem was resolved by a friend, and the user expressed gratitude for the assistance. The thread highlights the importance of clear communication and access to resources in problem-solving.

Homework Equations




\vec{\upsilon}= \vec{\Delta} V / ( B d)

\vec{\upsilon}= u E

The Attempt at a Solution



from the diagram , we have \vec{\upsilon} = 1.25*10^-5 V/(B)(0.001m)

using the second formula ( 1.25*10^-5 )V/(B)(0.001m) = 3.5*10^-5 (240V)(0.12m)


in which I got B = 1.7857*10^-7, which is wrong...
why?

Thank you very much for info, I was wondering why no1 bother to reply...
The link somehow manage to show a picture on my computer.

Well, the question have been solved by my friend. It is no longer a problem.
Thank you again for telling me though
 

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'

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...
