How Does Charge Affect Electric Field in Spherical Shells?

AI Thread Summary
The discussion centers on determining the electric field within and outside spherical shells with varying charges. It confirms that for a spherical shell with a net charge of -Q, the electric field at points outside the shell (r > b) is zero. The relationship between electric flux and charge is highlighted, emphasizing the equation Flux = E*A = q/epsilon0. Additionally, it references a video for further clarification on the topic. Understanding these principles is crucial for solving related physics problems.

Homework Statement


What is the electric field if r=a and r=b?
Reference:http://www.youtube.com/watch?v=BcuQ2c_WrMc"

2:11

And what if the net charge is just -Q on the conductor instead of -3Q? Will the electric field at r>b be 0?
Reference: Same video, 3:00-3:10

Hello Hooke's_Law.

Yes, then E=0 for r>b .
 
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...
