AI Thread Summary
The discussion revolves around solving the equation Q = Q0(e^(-t/RC)) for a specific homework problem. The user seeks clarification on the value of R to use in part C, noting that R2 and R3 are in series when the switch opens, leading to an answer of 0.166 seconds. There was initial confusion regarding the configuration of R2 and R3, as the user mistakenly thought they were in parallel. Ultimately, the user acknowledges the correct series connection, which resolves their confusion. Understanding the circuit configuration is crucial for solving the problem accurately.

Q= Q0(e^(-t/RC))

The Attempt at a Solution



I need help for part C.I am confused as to what value I should put for R.

The answer is supposed to be .166 seconds

R2 and R3 are in series when the switch opens. Did you get parts a) and b) right?

Find when Q=.25*Q0
 
I was confused because I thought R2 R3 were connected in parallel, but I see why they are in series now. Thanks

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...
