AI Thread Summary
The discussion centers on the confusion surrounding the electric field equation E = 7.35i - 5.63(y2 + 9.74)j and its implications in solving the Gaussian Cube question. Participants express difficulty in grasping the notation and concept of the electric field represented by the equation. There is a specific inquiry about calculating the net flux, indicating a need for clarification on this aspect of the problem. Understanding vector notation is acknowledged, but the focus remains on the calculation of net flux. The conversation highlights the challenges faced in applying theoretical concepts to practical problems in physics.

Okay I totally don't understand this problem at all. There is an example in the book also, but I just don't understand how to do it. Like the whole concept of how the E is written. I don't understand what this means: E = 7.35i - 5.63(y2 + 9.74)j.

I figured out the concept behind the vector notation of the eletric field. But now the only thing I don't understand is what is the net flux. How do I calculate the next flux.

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 hanged 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...
