1. Pinnu agbara ina ni aaye kan ti o wa ni 1 cm lati gbigba agbara 5.0 μ C. Konstantinu Coulomb (k) = 9 x 10 ⁹ Nm ² C ⁻² , 1 μC = 10 ⁻⁶ C.

A mọ̀:

Ijinna lati agbara (r) = 1 cm = 1/100 m = 0.01 m = 10 ^-2 m

Agbara (q) = 5.0 μ C = 5.0 x 10 ^-6 C

Àìyípadà Coulomb (k) = 9 x 10 ⁹ Nm ² C ⁻²

A nfẹ : Agbara ina (V)

Ojutu:

2. agbara Q₁ = 5.0 μC ati idiyele Q₂ = 6.0 μC. Àkókò tí ó dúró ṣinṣin ti Coulomb (k) = 9 x 10⁹ Nm²C^-2, 1 μC = 10^-6 C. Ojuami A wa laarin awọn idiyele naa. Pinnu agbara ina ni aaye A.

A mọ̀:

Gbigba agbara Q ₁ = -5.0 μ C = -5.0 x 10 ^-6 C

Ijinna aaye A lati Q ₁ = 10 cm = 0.1 m = 10 ^-1 m

Gbigba agbara Q ₂ = 6.0 μ C = 6.0 x 10 ^-6 C

Ijinna aaye a lati Q ₂ = 10 cm = 0.1 m = 10 ^-1 m

Àìyípadà Coulomb (k) = 9 x 10 ⁹ Nm ² C ⁻²
