Answer:
Reactance
Explanation:
In an AC circuit, the capacitive reactance of a capacitor is given by:
where
f is the frequency of the AC current
C is the capacitance of the capacitor
The reactance of the capacitor tells somehow the "resistance" of the capacitor to the passage of current through it. In fact:
- When the frequency of the AC current is zero (this means, we are in regime of DC current), the reactance becomes infinite, and this is true because the capacitor does not let the current pass through it)
- When the frequency of the AC current tends to infinite, the reactance becomes zero, and this is true because in this case the current changes direction so fast that the capacitor has not enough time to "block" the current, so the current almost no feels the presence of the capacitor.
Answer:
attractive toward +x axis is the net horizontal force
attractive toward +y axis is the net vertical force
Explanation:
Given:
- charge at origin,
- magnitude of second charge,
- magnitude of third charge,
- position of second charge,
- position of third charge,
<u>Now the distance between the charge at at origin and the second charge:</u>
<u>Now the distance between the charge at at origin and the third charge:</u>
<u>Now the force due to second charge:</u>
attractive towards +y
<u>Now the force due to third charge:</u>
attractive
<u>Now the its horizontal component:</u>
attractive toward +x axis
<u>Now the its vertical component:</u>
upwards attractive
Now the net vertical force:
