Hi, I'm trying to conceptualize the idea of work done by an electric field, can someone let me know if my reasoning is right? For a +ve charge, if it is moved against the electric field, the Electric Field does -ve work (W=-PE = -qV = (-)(+)(-)) For a -ve charge, however, if it is moved...

Sorry for the second equation, since Q=CV also, it can be substituted into make an equation of PE = Q^2 / 2C. So are you saying that in the since case there is no V between the capacitors, and thus the 1/2 is used? ALso, when it says electrons are "transferred", does that mean through the...

There are these two homework questions that I think are asking the exact same thing, yet use different equations (and get different answers for them) First Question 1. Homework Statement A potential difference of 10V is present between the plates of a capacitor. How much work must be done...

I'm having a hard time picturing this in my mind: Calculate the largest possible angle as viewed from Earth between the Sun and a hypothetical planet orbiting the Sun in a circular orbit with a=0.65 AU. Assume Earth's orbit is circular and that Earth and the hypothetical planet orbit the...

Great, thanks a lot ...that link is very helpful

So it was basic to figure out the masses and such, but I'm not exactly sure what the "orbital separation" really is? Can someone enlighten me? Here is the question for reference: A moon with a mass one quarter that of its parent planet orbits that planet with a period of 12 days. The mass of...
