Answer:
The charge resides on the outer surface = C
Explanation:
Surface area of cell
Separation between two plate
Dielectric constant
Potential difference
The capacitance of parallel plate capacitor in free space is given by,
Where permittivity of free space =
The Capacitance of capacitor is increase by times when it placed in dielectric medium.
And we know that,
So charge on the outer surface is given by,
Answer:
0.72 Hz minimum frequency
Explanation:
When the damping is negligible,Amplitude is given as
here = (6.30)/(0.135) = 46.67 N/m kg
= 1.70/(0.135)(0.480) = 26.2 N/m kg
From the above equation , rearranging for ω,
⇒ ω² =46.67 ± 26.2 = 72.87 or 20.47
⇒ ω = 8.53 or 4.52 rad/s
Frequency = f
ω=2 π f
⇒ f = ω / 2π = 8.53 /6.28 or 4.52 / 6.28 = 1.36 Hz or 0.72 Hz
The lower frequency is 0.72 Hz and higher is 1.36 Hz
