Answer:
density is defined as the amount of mass contained in unit volume of a body .its si unit is kg/m*3
Answer:
k = 2.279
Explanation:
Given:
Magnitude of charge on each plate, Q = 172 μC
Now,
the capacitance, C of a capacitor is given as:
C = Q/V
where,
V is the potential difference
Thus, the capacitance due to the charge of 172 μC will be
C = ![\frac{(172\ \mu C)}{V}](https://tex.z-dn.net/?f=%5Cfrac%7B%28172%5C%20%5Cmu%20C%29%7D%7BV%7D)
Now, when the when the additional charge is accumulated
the capacitance (C') will be
C' = ![\frac{(172+220)\ \mu C)}{V}](https://tex.z-dn.net/?f=%5Cfrac%7B%28172%2B220%29%5C%20%5Cmu%20C%29%7D%7BV%7D)
or
C' = ![\frac{(392)\ \mu C)}{V}](https://tex.z-dn.net/?f=%5Cfrac%7B%28392%29%5C%20%5Cmu%20C%29%7D%7BV%7D)
now the dielectric constant (k) is given as:
![k=\frac{C'}{C}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7BC%27%7D%7BC%7D)
substituting the values, we get
![k=\frac{\frac{(392\ \mu C)}{V}}{\frac{(172)\ \mu C)}{V}}](https://tex.z-dn.net/?f=k%3D%5Cfrac%7B%5Cfrac%7B%28392%5C%20%5Cmu%20C%29%7D%7BV%7D%7D%7B%5Cfrac%7B%28172%29%5C%20%5Cmu%20C%29%7D%7BV%7D%7D)
or
k = 2.279
