Answer : Distance, d=6.98 × 10⁷ Km

Explanation :

Given that,

Mass of the sun, m₁ = 1.99 × 10³⁰ kg

Mass of Mercury, m₂ = 3.30 × 10²³ kg

Gravitational force between the sun and mercury, F = 8.99 × 10²¹ N

According to Universal law of gravitation,

F=Gdfrac{m_1m_2}{d^2}

d is the distance of mercury from the sun

d=sqrt{dfrac{Gm_1m_2}{F}}

d=sqrt{dfrac{6.67times 10^{-11}times 1.99times {30}times 3.30times 10^{23}}{8.99times 10^{21}}}

d=sqrt{4.87times 10^{21}} m

d=6.98times 10^{10} m

or

d=6.98times 10^{7} Km

So, mercury is 6.98times 10^{7} Km far from the sun.
