Potential difference problem (important)

AI Thread Summary
To find the potential difference at the midpoint of the base of an equilateral triangle with each side measuring 3.61 cm and a charge of -0.34 mC at each vertex, the potential at that point must be calculated using the formula V = kq/r. The distance from each vertex to the midpoint of the base needs to be determined to apply this formula correctly. After calculating the potential contributions from all three charges, these values should be summed to find the total potential at the midpoint. The potential difference can then be analyzed based on the results obtained.

You have to show some work. Where are you stuck? You must calculate the potential of each charge at that point and add the three results.
 

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...
