A cylindrical capacitor is made of two thin-walled concentric cylinders. The inner cylinder has radius , and the outer one a rad

lianna [129]

Answer: $9.6\times 10^{-8} J$

Explanation:

The capacitance of cylindrical capacitor is

C= $\frac{2\pi \varepsilon _0L}{\ln\frac{r_2}{r_1}}$

C= $\frac{2\pi \times 8.854\times 10^{-12}\times 150}{\ln\frac{8}{4}}$

C= $1.2\times 10^{-8} F$

potential Energy stored in capacitor= $\frac{1}{2}CV^2$

= $\frac{1}{2}\times 1.2\times 10^{-8}\times 4^2$

= $9.6\times 10^{-8} J$

A parallel-plate capacitor with circular plates of radius 0.19 m is being discharged. A circular loop of radius 0.28 m is concen

aliina [53]

Answer:

$\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s$

Explanation:

Given that

R= 0.19 m

r= 0.28 m

I= 2.6 A

We know that

$I_D=\epsilon _oA\dfrac{dE}{dt}$

A= Area of loop

dE/dt= rate of change of electric filed

I=Displacement current

Here r>R

So A=π R²

Now by putting the values

$I=\epsilon _oA\dfrac{dE}{dt}$

$2.6=8.85\times 10^{-12}\times \pi\times 0.19^2\dfrac{dE}{dt}$

$\dfrac{dE}{dt}=2.59\times 10^{12}\ V/m.s$

State and explain the principle of superposition of electrostatic force

ella [17]

Answer:

The principle of superposition states that when a number of charges are interacting, the net electrostatic force a given charge is the vector sum of the forces exerted on it due to all other charges. The force between two charges is not affected by the presence of other charges.

Which type of force can be in the same it opposite direction?

LuckyWell [14K]

Answer:

C) unbalanced

Explanation:

Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion. When you add equal forces in opposite direction, the net force is zero.
