Question

Two solid spherical planets of equal radii r having masses 4m and 9m have their center seperated by distance 6r

Answer 1

Answer:

radil r having masses 4m and 9m have their center seperated by distance 6r two solid spherical planet of equal radil.

Answer 2

Distance of the Point is 12R/5

Explanation:

• Whenever the field is Zero then the Gravitational Force is ZERO.

• The field will be getting Cancelled owing to the reason that the field direction of both of them is Opposite.

• Let "x" be the distance of the planet from mass 4M having the field = zero

$\frac {G4M}{X^2} = \frac {G9M}{(6R - X)^2}$

X = $\frac {\sqrt (G4M)6R} {\sqrt G4M + \sqrt G9M}$

= $\frac {12}{5}R$ distance from the planet of mass 4M the force will be zero.
