Answer:
60 V
Explanation:
Let the potential on capacitor be V . This will be equal to voltage of the source .
During discharge this voltage of capacitor will create current .
V / 120 = .5
V = 60 V
So this would have been the voltage of the source . So voltage of source
= 60 V
Answer:
Explanation:
The charge on one object, 
The distance between the charges, r = 0.22 m
The force between the charges, F = 4,550 N
Let q₂ is the charge on the other sphere. The electrostatic force between two charges is given by the formula as follows :
So, the charge on the other sphere is 
.
Answer:
false
Explanation:
I'm pretty sure that's false.
We know that force <span>for a linear spring is equal to F=kx. Since energy is the potential to do work, and the spring is assumed to be perfectly elastic. Work can be written as:
W = F (integral sign) d</span>x
Therefore,
<span>W=k(Δx<span>)^2 / 2
W = F </span></span>Δx / 2
<span>W = 120 (2.0) / 2
W = 120
</span>
