My course

why for the Fx equation are you using 50 degrees and not 30 degrees like you did for the net F eqaution where you used 20 degrees b/c you lined it up with the r vector?

BP_655Wonderful reasoning.

We start here - Both buses start out with the same number of people, no one really feels the need to move (Or keep changing positions in equal numbers such that the balance is maintained). This is the case because materials have equal positives in the nucleus as surrounding electrons.

We use energy to destabilize the bus. Here is where it gets tricky - a destabilized bus can destabilize other buses - This is how a charged object charges other objects.

Hey, I'm wondering why the electrons in the conduction experiment shown would be more attracted to the positive charges in the conductor than to the available positive charges they were with originally. Thanks!
