Answer 1

Answer: $F=\frac{3}{4} \frac{GM^{2}}{d^{2}}$

Explanation:

According to Newton's law of Gravitation for the first case:

$F_{o}=G\frac{(M)(M)}{d^2}=\frac{GM^2}{d^2}$  (1)

Where:

$F_{o}$ is the gravitational force

$G$ is the Gravitational Constant

$M$ is the mass of each container

$d$  is the distance between both containers

Now, for the second case the mass of the first container is $1.5 M$ and the second $0.5 M$:

$F=G\frac{(1.5 M)(0.5 M)}{d^{2}}$ (2)

Finally:

$F=\frac{3}{4} \frac{GM^{2}}{d^{2}}$
