Whakaoti i te F=Kfrac{Q_{1}Q_{2}}{r_{2}}

$$F = K \frac { Q _ { 1 } Q _ { 2 } } { r _ { 2 } }$$

Whakaoti mō K (complex solution)

$$\left\{\begin{matrix}K=\frac{Fr_{2}}{Q_{1}Q_{2}}\text{, }&Q_{2}\neq 0\text{ and }Q_{1}\neq 0\text{ and }r_{2}\neq 0\\K\in \mathrm{C}\text{, }&\left(Q_{2}=0\text{ or }Q_{1}=0\right)\text{ and }F=0\text{ and }r_{2}\neq 0\end{matrix}\right.$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Whakareatia ngā taha e rua o te whārite ki te r_{2}.

$$Fr_{2}=KQ_{1}Q_{2}$$

Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.

$$KQ_{1}Q_{2}=Fr_{2}$$

He hanga arowhānui tō te whārite.

$$Q_{1}Q_{2}K=Fr_{2}$$

Whakawehea ngā taha e rua ki te Q_{1}Q_{2}.

$$\frac{Q_{1}Q_{2}K}{Q_{1}Q_{2}}=\frac{Fr_{2}}{Q_{1}Q_{2}}$$

Mā te whakawehe ki te Q_{1}Q_{2} ka wetekia te whakareanga ki te Q_{1}Q_{2}.

$$K=\frac{Fr_{2}}{Q_{1}Q_{2}}$$

Whakaoti mō K

$$\left\{\begin{matrix}K=\frac{Fr_{2}}{Q_{1}Q_{2}}\text{, }&Q_{2}\neq 0\text{ and }Q_{1}\neq 0\text{ and }r_{2}\neq 0\\K\in \mathrm{R}\text{, }&\left(Q_{2}=0\text{ or }Q_{1}=0\right)\text{ and }F=0\text{ and }r_{2}\neq 0\end{matrix}\right.$$
