Physics - Gravitation Question with Solution | TestHub

If$x$is the distance of point on the line joining the two masses from mass$m_2\prime$where gravitational field intensity is zero, then

$\frac{Gm}{{\left(r-x\right)}^2}=\frac{G{m}_2}{x^2}$or$\frac{2}{{\left(9-x\right)}^2}=\frac{8}{x^2}$

or$\frac{1}{9-x}=\frac{2}{x}$

On solving,$x=\mathrm{6 }\mathrm{m}$
