ʻO ke ana uila - nā pilikia a me nā hoʻonā

1. E hoʻoholo i ka hiki ke uila ma kahi kiko i loaʻa ma 1 kenimika mai kahi hoʻouku 5.0 μC. ʻO ke kūpaʻa Coulomb (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C.

ʻIke ʻia:

Ka mamao mai ka uku ʻana (r) = 1 kenimika = 1/100 m = 0.01 m = 10^-2 m

kauoha (q) = 5.0 μC = 5.0 x 10^-6 C

Paʻa Coulomb (k) = 9 x 10⁹ Nm²C^-2

Makemake ʻia: Ka hiki ke uila (V)

Lōlā:

Ka hiki ke uila:

ʻO ka hiki ke uila 4.5 m 10⁶ Volt

2. kauoha Q₁ = 5.0 μC a hoʻouku Q₂ = 6.0 μC. ʻO ke kūpaʻa o Coulomb (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C. Aia ke kiko A ma waena o nā uku. E hoʻoholo i ka hiki ke uila ma ke kiko A.

ʻIke ʻia:

kauoha Q₁ = -5.0 μC = -5.0 x 10^-6 C

ka mamao o ke kiko A mai Q₁ = 10 kenimika = 0.1 m = 10^-1 m

kauoha Q₂ = 6.0 μC = 6.0 x 10^-6 C

Ka mamao o ke kiko a mai Q₂ = 10 kenimika = 0.1 m = 10^-1 m

ʻO ke kūpaʻa o Coulomb (k) = 9 x 10⁹ Nm²C^-2

Makemake ʻia: Ka hiki ke uila ma ke kiko A

Lōlā:

Ka hiki ke uila 1 :

Ka hiki ke uila 2 :

Ka hiki ke uila ma ke kiko A :

V = V₂ - V₁

V = (54 – 45) x 10⁴

V = 9 x 10⁴

3. kauoha q₁ = 5.0 μC a hoʻouku q₂ = 6.0 μC. ʻO ke kūpaʻa o Coulomb (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C. E hoʻoholo i ka hiki ke uila ma ke kiko A.

ʻIke ʻia:

kauoha Q₁ = -5.0 μC = -5.0 x 10^-6 C

Ka mamao o ke kiko A mai Q₁ = 40 kenimika = 0.4 m = 4 x 10^-1 m

kauoha Q₂ = 6.0 μC = 6.0 x 10^-6 C

Ka mamao o ke kiko A mai Q₂ = 50 kenimika = 0.5 m = 5 x 10^-1 m

ʻO ke kūpaʻa o Coulomb (k) = 9 x 10⁹ Nm²C^-2

Makemake ʻia: Ka hiki ke uila ma kahi kiko A

Lōlā:

Ka hiki ke uila 1 :

Ka hiki ke uila 2 :

Ka hiki ke uila ma ke kiko A :

V = V₁ + V₂

V = (-11.25 + 10.8) x 10⁴

V = -0.45 x 10⁴

V = -4.5 x 10³

ʻO ka hiki ke uila ma ke kiko A -4.5 x 10³ Volt
