Electric Potential and Gauss' Laws Stuff (I think)

AI Thread Summary
The discussion revolves around understanding electric potential and Gauss' Law in a physics homework context. The user expresses confusion regarding the calculus involved, particularly in deriving the expression for dq. There is a question about the origin of the factor 2π in the equation dq=λ2πdy. The user is seeking clarity on the concepts and feels unsupported due to a lack of tutoring resources at their school. Overall, the thread highlights challenges in grasping complex physics topics and the need for better educational support.

The Attempt at a Solution



a) i think dq=\lambda2\pidy

Some of the calculus that we are using I am shaky on and I just don't understand what is being asked here. The others I really am not sure of. I am trying to develop a better understanding but my school offers no tutoring and my professor is virtually a robot.

You wrote dq=λ2π dy.

Where does the 2π come from?

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...
