How can I calculate the electric field using the voltage and gradient?

AI Thread Summary
To calculate the electric field using voltage and gradient, the formula E = -∇V is essential. The user has determined the voltage for a specific condition but is unsure how to apply the formula correctly. A suggestion was made to provide the question and attempts in text form instead of a file for better assistance. The lack of a file hindered the discussion, emphasizing the importance of clear communication. Providing detailed information will facilitate more effective help in solving the problem.

I listed all my problem in the file below

I have figure out the V of that condition,

but I do not know how to use E= -delV at this eg.

erm … there is no file :redface: …

but anyway it would be a lot easier for us if you would take the time to type out your question and your attempt for us (on the homework template, of course) :wink:
 

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...
