An ideal parallel-plate capacitor consists of a set of two parallel plates of area A separated by a very small distance d. When

the capacitor plates carry charges + Q and - Q, the capacitor stores energy U 0. If the separation between the plates is doubled, how much electrical energy is stored in the capacitor?

Answer:

2dQ²/2εA = 2U₀

Explanation:

The energy stored in the ideal parallel plate capacitor U = Q²/2C. For a parallel plate capacitor, C = εA/d where A is the area between the plates and D is the distance between them. So

U = Q²/2C = Q²/2εA/d = dQ²/2εA. At distance d₁ = d, U = U₀,

U₀ = dQ²/2εA,

When d₂ = 2d, U₁ = d₂Q²/2εA = 2dQ²/2εA = 2U₀

How is Coulomb’s law similar to newton’s law of gravitational force? How is it different
natulia [17]

The similarities and the differences between gravitational and electric force are listed below

Explanation:

- The magnitude of the gravitational force between two objects is given by Newton's law of gravitation:

F=G\frac{m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m_1, m_2 are the masses of the two objects

r is the separation between them

- Coloumb's law gives instead the strength of the electrostatic force between two charged objects, which is

F=k\frac{q_1 q_2}{r^2}

where:

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1, q_2 are the two charges

r is the separation between the two charges

By comparing the two equations, we find the following similarities:

  • Both the forces are inversely proportional to the square of the distance between the two objects, F\propto \frac{1}{r^2}
  • Both the forces are proportional to the product between the "main quantity" of each force, which is the mass for the gravitational force (F\propto m_1 m_2) and the charge for the electric force (F\propto q_1 q_2

Instead, we have the following differences:

  • The gravitational force is always attractive, since the sign of m is always positive, while the electric force can be either attractive or repulsive, since the sign of q can be either positive or negative
  • The value of the gravitational costant G is much smaller than the value of the Coulomb's constant, so the gravitational force is much weaker than the electric force
