Impedance is basically the overall resistance/impeding factor against a current in an electrical circuit. Inductive and capacitive reactances are used in a formula to DETERMINE impedance (it uses resistance too) and they are basically the opposition towards a current caused by the inductor (ex. coil) and a capacitor, respectively, in an LC or RLC circuit.

A capacitor of capacitance C has charge Q and stored energy is U if the charge is increased to 2Q then energy will be A)4U B)2U

Lubov Fominskaja [6]

Answer:

Explanation:

W = Vq

q = CV

W = V.CV

W = CV²

W/C = V²

V = √(W/C)

√(W1/C1) = √(W2/C2)

√(u/c) = √(x/2c)

x = 2u

Force on the particle is defined as the application of the force field of one particle on another particle. The magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

<h3>What is electrical force?</h3>

Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.

The given data in the problem is

q₁ is the negative charge = 6 µC=6×10⁻⁶ C

q₂ is the positive charge = 3 µC=3×10⁻⁶ C

r is the distance between the charges=0.002 m

$F_E$ is the electric force =?
