2.25 N

Explanation:

The formula for mechanical advantage is:

$Mechanical \ Advantage = \frac{F_o}{F_i}$

F_o stands for output force and F_i stands for input force.

We can plug in the given forces into the equation:

$Mechanical \ Advantage = \frac{450\ N}{200\ N}=2.25 \ N$

F_r=0.132:0.25

Explanation:

From the question we are told that:

$M_1=M*\frac{1}{6.334}$

Therefore

$M_2=M-M*\frac_{1}{6.334}$

$M_2=M*\frac{5.334}{6.334}$

Generally the equation for Gravitational force of attraction is mathematically given by

For Unequal split

$F=\frac{GM_1M_2}{d^2}$

$F=\frac{G(M*\frac_{1}{6.334})(M*\frac{5.334}{6.334})}{d^2}$

$F=\frac{GM^2}{d^2}*(0.132)$

For equal split

$F=\frac{GM_1M_2}{d^2}$

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

$F=0.25 \frac{GM^2}{d^2}$

Therefore the ratio of the gravitational force is

F_r=0.132:0.25
