The gravitational force between two massive objects is directly proportional to the product of masses. The value of the gravitational force between Mars and Phobos is $5. 16 \times 10^2^1 \rm \ N$ .

<h2></h2><h2>Newton's law of universal gravitation: </h2>

$F=G{\dfrac{m_1m_2}{r^2}}$

Where,

$F$ = Force

$G$ = Gravitational constant = $\bold {6.67 x 10^{-11 }}$ N.m²/kg²

$m_1$ = Mass of Mars = $\bold {6. 42 \times 10^{23 }\rm \ kg}$

$m_2$ = Mass of Phobos = $\bold {1.06 \times 10^{16 }\rm \ kg}$

$r$ = Distance between centers of the masses = 9378 km

Put the values in the formula,

$F=\bold {6.67 x 10^{-11 }}{\dfrac{\bold {6. 42 \times 10^{23 }\rm \ kg}\times \bold {1.06 \times 10^{16 }\rm \ kg}}{9378 ^2}}\\\\F= 5. 16 \times 10^2^1 \rm \ N$

Therefore, the value of the gravitational force between Mars and Phobos is $5. 16 \times 10^2^1 \rm \ N$ .
