I was reading my text and doing some problems and I realize that I am having a lot of issues understanding some of the basic stuff :(
I have a few questions about charge, fields etc. Like given the charge on an object after charge has been transferred by rubbing, how do you tell how many electrons have been transferred to the newly charged object? Do I use the equation for charge (q = [Np - Ne]e) ?
I was also reviewing E = F/q and am wondering:
- if E = F/q , can we say that this is because the force gets 'spread out' over the size of the charge? How would I draw how the force is acting upon a point charge?
- If I play around with this equation, I notice that when the charge is small, the electric field is big, and vice versa. Does this imply that a smaller electric field or force will be felt on a larger charge? Can a large point charge feel a large force / field?
Basically, I'm having trouble picturing what's going on in these two situations on the micro-level. (PS I hope this isn't in the wrong topic - I'm new to the forum :) )
