Insulating spherical shell prob

AI Thread Summary
To calculate the electric field in the region between the inner and outer insulating spherical shells (where a < radius < b), the formula q/(4*pi*Epsilon 0*(b-a)^2) is proposed. The discussion raises a question about the expectation of a constant electric field in this intermediate region. It is important to note that the electric field is influenced by the charge distribution and the geometry of the shells. The uniform distribution of charge on the inner shell leads to a radial electric field that decreases with distance from the center. Understanding these principles is crucial for accurately determining the electric field in this scenario.

A small, insulating, spherical shell with inner radius a and outer radius b is concentric with a larger insulating spherical shell with inner radius c and outer radius d. The inner shell has total charge +q distributed uniformly over its volume, and the outer shell has charge -q distributed uniformly over its volume.

How would i calculate the magnitude of the electric field for a < radius < b?

Would this forumla be correct?

q/(4*pi*Epsilon 0*(b-a)^2)

Why would you expect the electric field to be constant in the intermediate region?

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...
