Answer:
2.5
Explanation:
The capacitance of a parallel-plate capacitor filled with dielectric is given by
where
k is the dielectric constant
is the capacitance of the capacitor without dielectric
In this problem,
is the capacitance of the capacitor in air
is the capacitance with the dielectric inserted
Solving the equation for k, we find
Answer:
4x
Explanation:
Use to do the question.
For first instance,
-------------------( 1 )
for second instance,
-----------------( 2 )
So by (1) and (2),
s = 4x
