Answer:
(A) Total energy will be equal to
(b) Energy density will be equal to
Explanation:
We have given diameter of the plate d = 2 cm = 0.02 m
So area of the plate
Distance between the plates d = 0.50 mm =
Permitivity of free space
Potential difference V =200 volt
Capacitance between the plate is equal to
(a) Total energy stored in the capacitor is equal to
(b) Volume will be equal to , here A is area and d is distance between plates
So energy density
Answer:
x = 0.0537 m or 5.37 cm
Explanation:
Given:
spring constant'k'= 4900 N/m
radius 'r' =0.029 m
Area 'A' =r²π = 0.029²π => 2.6 x m²
Here, Pressure 'P' is given by,
Pressure = Force / Area
And we know that, for a spring :
F = kx, where k is the spring constant and x is the change in length.
P = kx/A
As P = 101325 Pa
101325 = 4900x / ( 2.6 x )
x = 0.0537 m or 5.37 cm
