General Questions about Eletric Field and Eletric Potential

AI Thread Summary
The discussion centers on clarifying concepts related to electric fields and electric potential. The participant seeks validation for their explanations regarding uniform electric fields and the implications of positive and negative charges on flux. They are encouraged to reconsider their understanding of electric potential differences between points A and B. The importance of accurately describing Gaussian surfaces and their relation to enclosed charges is emphasized. Overall, the thread aims to enhance comprehension of electric field dynamics and potential variations.

Hi! I have already write everything on the pictures(In attachment), I have already circled the correct answer, however, I am not sure explain it correctly. So, can you check my explanation or question?
Thanks!

Question Two: The electric field is uniform (constant). Why do you think it isn't? See http://www.studyphysics.ca/30/fields.pdf" to check your understanding of electric field lines.

Question Five: Yes. Since you are interested in the outward flux and the enclosed charge is positive, the flux through the surface is indeed, positive.

Question Six: You have the right idea, but I wouldn't use the word enclosed since the Gaussian surface doesn't enclose the negative charge. There is an additional [negative] contribution of flux through the left end cap due to the presence of the negative charge.

Question Seven: Are you sure that the electric potential is lower at A than B?

Question Eight: Again, are you sure that the electric potential is lower at A than B?

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
