F=G((m_{1}m_{2})/(d^2))

解答

F = G (\frac{m _{1} m _{2}}{d ^{2}})

d = \frac{G m _{1} m _{2}}{F}, d = - \frac{G m _{1} m _{2}}{F}; F \neq = 0

求解步骤

F = G (\frac{m _{1} m _{2}}{d ^{2}})

化简

G (\frac{m _{1} m _{2}}{d ^{2}}) : \frac{G m _{1} m _{2}}{d ^{2}}

F = \frac{G m _{1} m _{2}}{d ^{2}}

在两边乘以

d^{2}

F d^{2} = G m_{1} m_{2}

解

F d^{2} = G m_{1} m_{2} : d = \frac{G m _{1} m _{2}}{F}, d = - \frac{G m _{1} m _{2}}{F}; F \neq = 0

d = \frac{G m _{1} m _{2}}{F}, d = - \frac{G m _{1} m _{2}}{F}; F \neq = 0

\frac{20 n + 9}{n} = 21

\frac{4}{2 m} - \frac{2}{5 m} = 3

\frac{40}{x + 1} = \frac{15}{6}

so l v e f or y, x = \frac{z}{y}

\frac{q}{5 q - 4} = \frac{1}{3}
