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

解答

求解

r, F = \frac{G mm}{r ^{2}}

解答

r = \frac{m G}{F}, r = - \frac{m G}{F}; F \neq = 0

求解步骤

F = \frac{G mm}{r ^{2}}

化简

\frac{G mm}{r ^{2}} : \frac{m ^{2} G}{r ^{2}}

F = \frac{m ^{2} G}{r ^{2}}

在两边乘以

r^{2}

F r^{2} = m^{2} G

解

F r^{2} = m^{2} G : r = \frac{m G}{F}, r = - \frac{m G}{F}; F \neq = 0

r = \frac{m G}{F}, r = - \frac{m G}{F}; F \neq = 0

x + \frac{8}{x} = 6

\frac{15}{y} = 3

((8-m)*(m-8))/m =16

\frac{( 8 - m ) \cdot ( m - 8 )}{m} = 16

f(a)=8-8/a ,a=8

f (a) = 8 - \frac{8}{a}, a = 8

8 π = \frac{2 π}{b}
