solvefor r,F=(Kqq)/(r^2)

解

解く

r, F = \frac{K qq}{r ^{2}}

r = \frac{q K}{F}, r = - \frac{q K}{F}; F \neq = 0

解答ステップ

F = \frac{K qq}{r ^{2}}

簡素化

\frac{K qq}{r ^{2}} : \frac{q ^{2} K}{r ^{2}}

F = \frac{q ^{2} K}{r ^{2}}

以下で両辺を乗じる:

r^{2}

F r^{2} = q^{2} K

解く

F r^{2} = q^{2} K : r = \frac{q K}{F}, r = - \frac{q K}{F}; F \neq = 0

r = \frac{q K}{F}, r = - \frac{q K}{F}; F \neq = 0
