Electric Field of 2 charges on x-axis

AI Thread Summary
The discussion revolves around understanding the electric field produced by two charges on the x-axis, specifically addressing the differences between two scenarios labeled as part (a) and part (b). Participants emphasize the importance of considering the direction of the electric fields in addition to their magnitudes, as indicated by the equation |E| = (Kq)/r^2. A suggestion is made to sketch the electric fields near the charges to visualize their interactions and influences. Clarification is sought on how the two cases differ, highlighting that they are indeed distinct. Understanding these differences is crucial for solving the problem accurately.

I'm not really sure if there is a difference between part (a) and part (b)

Hello NPM, :welcome:

well, from your relevant equation I wouldn't be able to see a difference! You need something more, about the direction perhaps !

Can you sketch the fields close to the charges in the two cases (there the 'other charge' hasn't got much influence) ?

They are very different. Why? :smile:
 

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...
