Electric flux through a wedge shaped block

AI Thread Summary
The discussion revolves around determining the electric flux through a wedge-shaped block. Participants initially debate whether the answer is (E) or (D), with some asserting that the flux on opposite sides is zero. Clarification is provided that the problem specifically asks which face(s) have non-zero flux. Ultimately, the consensus indicates that the correct answer is (C). The focus remains on understanding the conditions under which electric flux is non-zero through the wedge's faces.

It's (D) , because the angle is 90 ( the surface is perpendicular to the field )

The answer is not (D). You are correct in saying that the flux through 4 and 5 is zero. However, the problem is asking "Through which face(s) in the wedge the flux is non-zero?".

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'
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'
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...
