Answer:
Explanation:
Newton's Gravitation Law
[tex]\displaystyle \frac{GmM}{d^2}[/tex]
where G is a constant, M and M the masses e d the distance betwen masses.
[tex]\displaystyle G\frac{5\cdot2}{x^2}=G\frac{6\cdot 2}{(2x+1)^2} \quad \sqrt{6}x=(2x+1)\sqrt {5} \quad x=\frac{\sqrt{5}}{\sqrt{6}-2\sqrt{5}}[/tex]
