I-voltage kagesi - izinkinga nezixazululo

1. Thola amandla kagesi endaweni etholakala ku-1 cm ukusuka ekushajeni okungu-5.0 μ C. I-Coulomb constant (k) = 9 x 10 ⁹ Nm ² C ⁻² , 1 μC = 10 ⁻⁶ C.

Kwaziwa:

Ibanga ukusuka ekushajeni (r) = 1 cm = 1/100 m = 0.01 m = 10 ^-2 m

Ishaja (q) = 5.0 μ C = 5.0 x 10 ^-6 C

I-Coulomb constant (k) = 9 x 10 ⁹ Nm ² C ⁻²

Okufunwayo: Amandla kagesi (V)

Isixazululo:

Amandla kagesi:

Amandla kagesi angama- 4.5 x 10 ⁶ Volts

2. Shaja Q₁ = 5.0 μC futhi ukhokhise Q₂ = 6.0 μC. I-Coulomb's njalo (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C. Iphuzu A liphakathi kwamacala. Thola amandla kagesi endaweni A.

Kwaziwa:

Ishaja Q ₁ = -5.0 μ C = -5.0 x 10 ^-6 C

Ibanga lephuzu A kusuka ku-Q ₁ = 10 cm = 0.1 m = 10 ^-1 m

Ishaja Q ₂ = 6.0 μ C = 6.0 x 10 ^-6 C

Ibanga lephuzu a kusukela ku -Q ₂ = 10 cm = 0.1 m = 10 ^-1 m

I-coulomb's constant (k) = 9 x 10 ⁹ Nm ² C ⁻²

Kufunwa: Amandla kagesi endaweni A

Isixazululo:

Amandla kagesi 1 :

Amandla kagesi 2 :

Amandla kagesi endaweni A :

V = V ₂ – V ₁

V = (54 – 45) x 10 ⁴

V = 9 x 10 ⁴

3. Shaja q₁ = 5.0 μC futhi ukhokhise q₂ = 6.0 μC. I-Coulomb's njalo (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C. Thola amandla kagesi endaweni A.

Kwaziwa:

Ishaja Q ₁ = -5.0 μ C = -5.0 x 10 ^-6 C

Ibanga lephuzu A kusuka ku -Q ₁ = 40 cm = 0.4 m = 4 x 10 ^-1 m

Ishaja Q ₂ = 6.0 μ C = 6.0 x 10 ^-6 C

Ibanga lephuzu A kusuka ku -Q ₂ = 50 cm = 0.5 m = 5 x 10 ^-1 m

I-coulomb's constant (k) = 9 x 10 ⁹ Nm ² C ⁻²

Kufunwa: Amandla kagesi endaweni A

Isixazululo:

Amandla kagesi 1 :

Amandla kagesi 2 :

Amandla kagesi endaweni A :

V = V ₁ + V ₂

V = (-11.25 + 10.8) x 10 ⁴

V = -0.45 x 10 ⁴

V = -4.5 x 10 ³

Amandla kagesi endaweni A angama --4.5 x 10 ³ Volts
