It does take on new set of proerties
The weight is in equilibrium, so the two forces acting on it (tension <em>T</em> pulling upward, and its own weight <em>W</em> pulling it downward) cancel each other. By Newton's second law,
∑ <em>F</em> = <em>T</em> - <em>W</em> = 0
so that
<em>T</em> = <em>W</em>
Calculate the object's weight:
<em>W</em> = (20 kg) (9.8 m/s²) = 196 N
So the tension is <em>T</em> = 196 N as well.
Explanation:
We have,
Radius of pizza, r = 18 m
Potential difference, V = 575 V
Stored electrical potential energy, E = 3.31 J
The area if an air-filled capacitor with parallel plates is equal to that of the pizza. It means,
The stored potential energy in a capacitor is given by :
C is capacitance
The formula of the capacitance of a parallel plate capacitor is given by :
d is plate separation of this capacitor
