It's both in and out.. but wouldn't the dec. part go to 0, and lead the B to become ½A..
I can see B would be as high as A in a short moment,should it not be ½A thereby lead B<A
Hey Pf..
I am trying to understand Lenz's law, but somehow it doesn't make sense.
In my book there is some checkpoints execise to test wheather you've understood what you read about, one those checkpoints looks like this.

Homework Statement
Find the Laplace transform of the following function
t[SUP]2[SUP] - 2t
The Attempt at a Solution
\[\begin{gathered}
f\left( t \right) = {t^2} - 2t \hfill \\
l\left( {f\left( t \right)} \right) = F\left( s \right) = \int_0^\infty {{e^{ - st}} \cdot \left( {{t^2} - 2t}...
Ahh.. I see what you mean now..
My drawings weren't correct..
But by using youre drawing I see that Cos(theta) = F_x/F <=> F_x = Fcos(theta)
So the expression for F_X = (q1q2/(4∏εo(d^2))) cos(theta)
