Electric Electric field Field Magnitude

AI Thread Summary

To find the magnitude of the electric field given a force of 14 N on a charge of 2.1E-9 C, the equation E = F/q can be used. The initial attempt to use E = Kq'/r^2 was hindered by the lack of distance information. The discussion highlights the importance of using the correct formula when calculating electric fields. Clarification on the use of E = F/q was provided, confirming its applicability in this scenario. Understanding the relationship between force, charge, and electric field is crucial for accurate calculations.

1. A force of 14 N exists on charge q, which is 2.1E-9 C. What is the magnitude of the electric field?

2. Relevant equation is E=Kq'/r^2

3. I attempted using the equation above but the question doesn't include any distance. Is there another equation I should use?

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
